Materials are deeply connected with the environment, because they stem from raw materials extracted from the geosphere, rely on large amounts of energy and of water in their production stage, project emissions to air, water and soil when their ores (or minerals) are mined, when they are made in steel mills or cement kilns, including very significant amounts of greenhouse gases. They also contribute to emissions and energy consumption of the artifacts of which they are part, either consumption or investment goods. Their connection with the biosphere raises many issues, in terms of toxicology, ecotoxicology or biodiversity or simply of public health or in the working place. Materials, as an essential part of the anthroposphere, interact deeply with the anthroposphere itself but also with the biosphere, the geosphere, the atmosphere and the hydrosphere, thus with nature in a general way through mechanisms which can no longer simply be described at the margin, as resource depletion or as pollution. This raises issues related to the sustainability of materials in human activities, in which they are deeply immersed and entangled. The standard way of dealing with these environmental issues is to invoke sustainability and to explain that all actors are engaged in sustainable development, a morals or an ethics that points in which direction to go: all players in the materials field, industry, institutions and research, claim allegiance to sustainable development. At a more technical level, specific tools like Life Cycle Assessment (LCA) are used extensively to measure the interaction of materials with the environment. This, however, is not enough to deal properly with the environmental issues of materials, because these issues are not marginal any longer: the anthroposphere has become so large with respect to the biosphere, the geosphere and the planet in general that environmental risk is now part of modern life, especially in connection with climate change and the loss of biodiversity. To go deeper in analyzing the connection of human activities with nature, it is therefore necessary to reach out to SSH (Social Science and Humanities) disciplines and particularly to environmental ethics. This is a prerequisite for materials scientists (and others) to act decisively in the future in the face of the danger that lies ahead of us. The present paper reviews the advances of environmental ethics, a fairly young discipline born in the 1970s, in as far as it can help all actors on the world anthropospheric theater choose their lines for the future in a more conscious and sophisticated way than simply claiming obedience to sustainability. We will review briefly intellectual forerunners of the discipline like Jean-Jacques Rousseau, Henri David Thoreau, Rachel Carson or Paul Ehrlich. This will help flesh out well-known concepts like the precautionary principle or the “polluter-pays” principle, which are invoked in creating new materials or new processes to keep pol
材料与环境有着深刻的联系,因为它们来源于从地圈中提取的原材料,在生产阶段依赖大量的能源和水,在开采矿石(或矿物)时,在钢铁厂或水泥窑中生产时,将排放物排放到空气、水和土壤中,包括大量的温室气体。它们还导致了它们所属的人工制品的排放和能源消耗,无论是消费品还是投资品。它们与生物圈的联系引发了许多问题,包括毒理学、生态毒理学或生物多样性,或者仅仅是公共卫生或工作场所。物质作为人类圈的一个重要组成部分,与人类圈本身以及生物圈、地圈、大气层和水圈都有着深刻的相互作用,从而通过各种机制与自然产生了普遍的相互作用。这引发了与材料在人类活动中的可持续性有关的问题,这些材料深深地沉浸在其中并纠缠在一起。处理这些环境问题的标准方法是援引可持续性,并解释所有参与者都参与了可持续发展,这是一种道德或伦理,指明了前进的方向:材料领域、工业、机构和研究的所有参与者都声称忠于可持续发展。在更技术的层面上,生命周期评估(LCA)等特定工具被广泛用于测量材料与环境的相互作用。然而,这还不足以妥善处理材料的环境问题,因为这些问题不再是边缘问题:相对于生物圈、地圈和整个地球来说,人类圈已经变得如此之大,以至于环境风险现在已经成为现代生活的一部分,尤其是在气候变化和生物多样性丧失方面。为了更深入地分析人类活动与自然的联系,有必要深入社会科学与人文学科,特别是环境伦理学。这是材料科学家(和其他人)在未来面对摆在我们面前的危险时果断行动的先决条件。本文回顾了环境伦理学的进展,这是一门诞生于20世纪70年代的相当年轻的学科,只要它能帮助世界人类剧场的所有演员以一种更自觉、更复杂的方式为未来选择台词,而不是简单地宣称服从可持续发展。我们将简要回顾该学科的知识分子先驱,如让-雅克·卢梭、亨利·大卫·梭罗、雷切尔·卡森或保罗·埃利希。这将有助于充实众所周知的概念,如预防原则或“污染者付费”原则,这些概念在创造新材料或新工艺以控制污染和健康问题时被援引,这是职业道德和环境法约束的一部分。有必要质疑内在价值的关键概念附属于谁或附属于什么:人、所有生物或生态系统,即整个环境,从而定义人类中心主义、生物中心主义和生态中心主义。环境法和可持续发展伦理仍然主要以人类为中心,而科学生态学则更明显地以生态为中心。为了应对当今环境问题带来的挑战并避免灾难,未来所有社会参与者和物质世界的人们可能有必要遵循环境伦理的步骤,从人类中心主义上升到更广泛的生态中心主义视野。

A new innovation paradigm is needed to answer the societal, economic and environmental challenges the world and companies are facing. The EU funded Horizon 2020 SPIRE Project “Coordinating Optimisation of Complex Industrial Processes” (COCOP) is combining technological and social innovation within a steel company pilot case (Sidenor). The project aims at reducing raw materials consumption (and energy and emissions reduction as well) by plant-wide optimisation of production processes based on a software solution and at the same time changing social practices. Key for COCOP is a methodology integrating technological innovation within a social innovation process of co-creation and co-development by involving (potential) users of the future software system and relevant stakeholders right from the beginning; thereby improving effectiveness and impact of the innovations and the implementation process. This involvement is instructed and measured by social key performance indicators (social KPIs) and operationalised in surveys (questionnaire and interviews) with future users, engineers and external experts (from different industry sectors not involved in the project). The article presents the results of the starting point of COCOP illustrating the future user perspective of the pilot steel company (Sidenor) contrasted by the view of external experts – seriously taking into account the interfaces between technology, human and organisation.
需要一种新的创新模式来应对世界和公司面临的社会、经济和环境挑战。欧盟资助的地平线2020 SPIRE项目“复杂工业流程的协调优化”(COCOP)将技术和社会创新结合在钢铁公司试点案例(Sidenor)中。该项目旨在通过基于软件解决方案的全厂生产流程优化,同时改变社会实践,减少原材料消耗(以及能源和排放)。COCOP的关键是通过从一开始就让未来软件系统的(潜在)用户和相关利益相关者参与进来,将技术创新整合到共同创造和共同开发的社会创新过程中;从而提高创新和实施过程的有效性和影响力。这种参与由社会关键绩效指标(社会KPI)指导和衡量,并在对未来用户、工程师和外部专家(来自未参与项目的不同行业部门)的调查(问卷和访谈)中实施。本文介绍了COCOP起点的结果,说明了试点钢铁公司(Sidenor)与外部专家的观点对比的未来用户视角 – 认真考虑技术、人员和组织之间的接口。

The European Steel industry is spending considerable efforts in order to improve the socio-economic and environmental sustainability of its processes by promoting any development, which can increase efficiency and lower the environmental impact of the steel production processes. In particular, the European iron and steel sector is strongly committed toward the reduction of energy consumptions and CO2 emissions. Process gases are a very valuable resource: possibilities exist to consider these gases as an intermediate by-product for the production of other valuable energy carriers or products with an associated environmental benefit. Therefore, the process gas networks, especially inside the integrated steelworks, have a fundamental function, as they allow meeting the demand of many processes and producing energy through dedicated facilities. They can also support the production processes by internal electric energy generation and often by supplying energy outside the plant boundaries. On the other hand, such networks are very complex systems interacting with many different production steps and the management of such complex systems is a very difficult task, where many often-counteracting factors need to be jointly taken into account. This paper presents the first outcomes of the research project entitled “Optimization of the management of the process gas network within the integrated steelworks (GASNET)”, which aims at developing a Decision Support System helping the energy managers and other concerned technical personnel to implement an optimized off-gases management and exploitation considering environmental and economic objectives. A series of Key Performance Indicators has been elaborated, in order to monitor the efficiency of the gas management and the objectives of the optimization have been defined. The overall structure of the project and the ongoing work will also be outlined in the paper.
欧洲钢铁行业正在花费大量努力,通过促进任何发展来提高其生产过程的社会经济和环境可持续性,这些发展可以提高钢铁生产过程的效率并降低对环境的影响。特别是,欧洲钢铁行业坚决致力于减少能源消耗和二氧化碳排放。工艺气体是一种非常有价值的资源:有可能将这些气体视为生产其他有价值的能源载体或具有相关环境效益的产品的中间副产品。因此,工艺气体网络,尤其是综合钢铁厂内部的工艺气体网络具有基本功能,因为它们可以满足许多工艺的需求,并通过专用设施生产能源。它们还可以通过内部发电以及通常通过在工厂边界外供应能源来支持生产过程。另一方面,这种网络是与许多不同的生产步骤相互作用的非常复杂的系统,并且这种复杂系统的管理是一项非常困难的任务,其中需要共同考虑许多经常抵消的因素。本文介绍了题为“综合钢铁厂(GASNET)内工艺气体网络管理的优化”的研究项目的第一个成果,旨在开发决策支持系统,帮助能源管理人员和其他相关技术人员在考虑环境和经济目标的情况下实施优化的废气管理和开发。为了监测天然气管理的效率,制定了一系列关键绩效指标,并确定了优化目标。该文件还将概述该项目的总体结构和正在进行的工作。

FeAl20Si20 (wt.%) powders prepared by mechanical alloying from different initial feedstock materials (Fe, Al, Si, FeAl27) were investigated in this study. Scanning electron microscopy, X-ray diffraction and nanoindentation techniques were used to analyze microstructure, phase composition and mechanical properties (hardness and Young’s modulus). Finite element model was developed to account for the decrease in measured values of mechanical properties of powder particles with increasing penetration depth caused by surrounding soft resin used for embedding powder particles. Progressive homogenization of the powders’ microstructure and an increase of hardness and Young’s modulus with milling time were observed and the time for complete homogenization was estimated.

Ukraine’s commitments under Association Agreement: challenges and opportunities for the steel industry 乌克兰在联系国协定下的承诺:钢铁工业的挑战与机遇

The steel sector stands for a quarter of Ukraine’s industrial gross value added and is a backbone of the country’s economy. However, owing to lastingly insufficient investments to modernisation, the industry is largely obsolete: 70–80% of the production facilities are in operation beyond their final designed term of exploitation. Technology backwardness, coupled with excessive iron ore mining, results in an enormous environmental footprint. Owing to the domestic political and socioeconomic factors and severe competition on the global scale, the steel output hit its historic low in 2017. Recently, the EU became major Ukraine’s trade partner with steel export share of 32% in 2017. Modalities of this partnership will be gradually shaped in context of the EU-Ukraine Association Agreement (entered into force since 01.09.2017), which stipulates transposition into Ukrainian law of some European directives, potentially sensitive for the iron and steel sector. In this paper, the current state of Ukraine’s steel industry was analysed, focusing competitiveness and environmental impact. The analysis performed reveals that short-term implications of the Association Agreement may expose the Ukrainian steelmakers to additional costs; however, the need to comply with the EU regulations is seen as an important factor, motivating the steel industry to modernise and, in the long-term, improve its economic performance and reinforce competitiveness.
钢铁行业占乌克兰工业增加值总额的四分之一,是该国经济的支柱。然而,由于对现代化的长期投资不足,该行业在很大程度上已经过时:70-80%的生产设施在其最终设计的开发期限之外仍在运行。技术落后,再加上过度开采铁矿石,造成了巨大的环境足迹。由于国内政治和社会经济因素以及全球范围内的激烈竞争,2017年钢铁产量创下历史新低。最近,欧盟成为乌克兰的主要贸易伙伴,2017年钢铁出口份额为32%。这种伙伴关系的模式将在欧盟-乌克兰联系国协定(自2017年9月1日起生效)的背景下逐步形成,该协定规定将一些对钢铁行业可能敏感的欧洲指令转换为乌克兰法律。本文分析了乌克兰钢铁行业的现状,重点分析了竞争力和环境影响。所进行的分析表明,联系国协议的短期影响可能使乌克兰钢铁制造商面临额外的成本;然而,遵守欧盟法规的必要性被视为一个重要因素,促使钢铁行业实现现代化,并从长远来看,提高其经济表现和增强竞争力。

L’accumulation des sédiments en couche successives au fond des cours d’eau conduit à leur envasement. L’objectif de cette étude est de démontrer l’utilisation pratique des sédiments du port de Bethioua dans la fabrication des briques. Les sédiments ont été introduits dans le mélange de référence avec un taux de substitution de 20 % en tant que remplacement de l’argile utilisée pour la fabrication des briques. Des éprouvettes de briques de référence et de briques à base de sédiments marins de formes cylindriques ont été préparées en suivant le même processus de fabrication. Les éprouvettes de briques ont été cuites à des températures comprises entre 600 et 900 °C avec une durée de cuisson de 6 et 24 h. Elles ont ensuite été soumises à des essais de résistance à la compression. Les résultats obtenus ont montré que les briques à base de sédiments avec une substitution de 5 et 10 % présentent une meilleure résistance que les briques de référence. La substitution par des sédiments avec cette concentration augmente la résistance à la compression avec une faible température et une faible durée de cuisson. Les résultats de cette étude démontrent que la production de briques cuites avec les sédiments marins du port de Bethioua améliore nettement et donnent une meilleure résistance que la résistance de la brique de référence pour un ajout de 5 et 10 %. Le taux de 15 % donne une résistance comparable à celui de la résistance de la barbotine de brique.
沉积物在河流底部连续堆积,导致河流淤积。本研究的目的是证明贝提瓦港沉积物在砖制造中的实际应用。沉淀物被添加到参考混合物中,替代率为20%,以替代用于制造砖的粘土。采用相同的制造工艺制备了圆柱形参考砖和海洋沉积物砖样品。砖试样在600 - 900°C的温度下烘烤,烘烤时间为6 - 24小时。然后对它们进行抗压强度测试。结果表明,替代5%和10%的沉淀物基砖比参考砖具有更好的强度。用这种浓度的沉淀物替代,在低温和短蒸煮时间下增加了抗压强度。本研究结果表明,在贝提瓦港,用海洋沉积物烧制的砖的产量明显提高,在添加5%和10%的情况下,比参考砖的强度更好。15%的强度与砖轮的强度相当。

Detailed mechanisms of hydrogen charging and hydrogen stress cracking of steel in liquid ammonia storage 钢在液氨储存过程中的充氢和氢应力开裂机理
IF 0.9 Q4 Materials Science Pub Date : 2019-07-01 DOI: 10.1051/mattech/2019022
J. Crolet
When the unprecedented environmental cracking of steel in liquid ammonia was collectively studied, its undisputable “anodic character” was taken as the signature of a stress corrosion cracking mechanism, which is effectively the case in aqueous corrosion. Conversely, when the metallurgical precautions proved to be the same as in sour service, this strongly suggested a hydrogen stress cracking mechanism. In aqueous corrosion, however, this can only occur by cathodic hydrogen charging at low potential, and for 50 years, this basic contradiction could never be overcome. Actually, it occurs that the liquid ammonia solvent (NH3) is 50% richer in hydrogen than the water solvent (OH2), so that hydrogen gas can also be produced by a partial oxidisation into ½ N2 + H2. This therefore induces a theoretical possibility of an “anodic” hydrogen charging, or more exactly a protonic cathodic reaction only running at high potential on passive iron in oxygen contaminated ammonia. And once the detrimental potential is achieved through appropriate combinations of oxygen and water traces, the charging process becomes an autonomous oxidation-reduction at the steel surface NH3 → ½ N2 + H2 + (H+ + e−)steel. In Part II (Jean-Louis Crolet, Matériaux & Techniques 107, 402, 2019), this new assumption will be successfully confronted to all the factual data from both field and laboratory experience.
当对钢在液氨中史无前例的环境开裂进行综合研究时,将其无可争议的“阳极性”作为应力腐蚀开裂机制的标志,这在水腐蚀中是有效的。相反,当冶金预防措施被证明与酸性服务相同时,这强烈表明氢应力开裂机制。然而,在含水腐蚀中,这只能通过低电位的阴极氢充电来实现,并且50年来,这个基本矛盾永远无法克服。实际上,液态氨溶剂(NH3)的氢含量比水溶剂(OH2)高50%,因此氢气也可以通过部分氧化生成1 / 2 N2 + H2。因此,这就产生了一种理论上的“阳极”氢充电的可能性,或者更确切地说,是一种质子阴极反应,仅在氧污染的氨中的钝化铁上以高电位运行。一旦通过适当的氧和水的组合达到有害电位,充电过程就成为钢表面NH3→½N2 + H2 + (H+ + e−)钢的自主氧化还原过程。在第二部分(Jean-Louis Crolet, mat riaux & Techniques 107,402, 2019)中,这个新的假设将成功地面对来自现场和实验室经验的所有事实数据。

Ce travail évalue l’effet de la granulométrie du broyat de noyaux d’olive (BNO) sur les propriétés de la brique de terre cuite. Les noyaux d’olive concassés sont tamisés pour séparer les différents diamètres (1,5, 1, 0,5 et 0,25 mm). Nous avons confectionné quatre séries d’échantillons contenant 5, 10, 15 et 20 % de BNO dans la masse d’argile pour les essais. Les matières premières argile et BNO ont été caractérisées aux moyens d’analyses chimique et minéralogique, analyse thermique gravimétrique TG-DTG. Les propriétés physico-mécanique et thermique des éprouvettes cuites à 1000 °C, telles que, la porosité, l’absorption d’eau, la résistance à la compression, et la conductivité thermique ont été évaluées. Cette étude présente des résultats intéressants pour augmenter le pouvoir d’isolation des briques. Nous avons œuvré sur l’optimisation du diamètre de l’ajout, en travaillant sur la réduction des ponts thermiques et la diminution des transferts de chaleur dans les cavités produites par la consumation du BNO. Nous avons constaté que pour des diamètres plus petits de l’ajout; la conductivité thermique est de moindre avec des résistances à la compression avérées.
这项工作评估了磨碎橄榄核(BNO)粒度对陶土砖性能的影响。压碎的橄榄核经过筛分,以分离不同直径(1.5、1、0.5和0.25mm)。我们制备了四组样品,其中粘土质量中含有5%、10%、15%和20%的BNO进行测试。通过化学和矿物学分析、TG-DTG重量热分析对粘土和BNO原料进行了表征。评估了在1000°C下烧制的试样的物理机械和热性能,如孔隙率、吸水率、抗压强度和导热性。这项研究为提高砖的绝缘能力提供了有趣的结果。我们致力于优化添加剂的直径,致力于减少热桥和减少BNO消耗产生的空腔传热。我们发现,对于较小直径的添加剂;热导率较低,具有经证明的抗压强度。
