The Ti3SiC2 used in this project has been purchased ready-made. This study aimed to investigate the effect of sintering temperature on samples' microstructure and mechanical properties, including three-point flexural strength, Vickers hardness, and fracture toughness. Therefore, Ti3SiC2 samples were sintered under a vacuum atmosphere at a pressure of 35 MPa for 30 minutes at two temperatures of 1500 °C and 1550 °C by hot pressing. The microstructure obtained from the fracture cross-section of the samples shows that by increasing the sintering temperature to 1550 °C, the microstructure of this sample becomes larger than the sintered sample at 1500 °C. Also, increasing the sintering temperature to 1550 °C causes the decomposition of Ti3SiC2 to TiC, which can be seen in the X-ray diffraction pattern (XRD). In addition, the relative density of the sintered sample at 1550 °C is 98.08% which is higher than that of the sintered sample at 1500 °C with the result of 89%. On the other hand, the three-point flexural strength (227.5 MPa), the Vickers hardness (~9 GPa), and the fracture toughness (8.6 MPa.m1/2) of the sintered sample at 1500 °C are higher due to the fine-grained structure.
本项目所使用的Ti3SiC2材料是购买的现成材料。本研究旨在研究烧结温度对试样显微组织和力学性能的影响,包括三点抗弯强度、维氏硬度和断裂韧性。因此,采用热压法在1500℃和1550℃两个温度下,在压力为35 MPa的真空气氛下烧结Ti3SiC2样品30分钟。试样断口断面的显微组织表明,将烧结温度提高到1550℃后,试样的显微组织比1500℃时的烧结试样大。同时,将烧结温度提高到1550℃时,Ti3SiC2分解为TiC,这在x射线衍射图(XRD)中可以看出。1550℃烧结试样的相对密度为98.08%,高于1500℃烧结试样的89%。另一方面,烧结试样在1500℃时的三点抗弯强度(227.5 MPa)、维氏硬度(~9 GPa)和断裂韧性(8.6 MPa.m1/2)均因其细晶组织而提高。

In this research, the 2nd part of a series of papers on the processing and characterization of TiAl–Ti3AlC2 composites, the phase evolution during the manufacturing process was investigated by X-ray diffraction (XRD) analysis and Rietveld refinement method. Metallic Ti and Al powders with different amounts of previously-synthesized Ti3AlC2 additives (10, 15, 20, 25 and 30 wt%) were ball-milled and densified by spark plasma sintering (SPS) under 40 MPa for 7 min at 900 °C. Before the sintering process, XRD test verified that the powder mixtures contained metallic Ti and Al as well as Ti3AlC2 and TiC (lateral phase synthesized with Ti3AlC2) phases. In the sintered composites, the in-situ synthesis of TiAl and Ti3Al intermetallics as well as the presence of Ti3AlC2 and the formation and Ti2AlC MAX phases were disclosed. The weight percentage of each phase in the final composition of the samples and the crystallite size of different phases were calculated by the Rietveld refinement method based on the XRD patterns. The size of Ti3AlC2 crystallites in sintered samples was compared with the crystallite size of synthesized Ti3AlC2 powder.

CaTi1-x(Nb1/2Al1/2)xO3 with x=0.1-0.5 ceramics were processed  through solid state sintering. X-rays diffraction (XRD) patterns of the compositions showed that the samples have orthorhombic crystal structure with symmetry (Pbnm). The symmetry was further confirmed using Raman spectroscopy. A total of 13 Raman modes were detected, which were in agreement with the XRD results. Microstructure analysis of the samples showed porosity in the samples, presumably due to the substitution of Al, having high melting point. As the concentration of Al and Nb increased, relative permittivity (er), quality factor (Q×fo) and temperature coefficient of resonance frequency decreased. Optimum microwave dielectric properties were achieved for the composition x=0.5 sintered at 1650 °C for 8 h i.e., er ~27.09, Q×fo ~17378 GHz and tf ~ -2.5 ppm/°C.
采用固态烧结法制备了x=0.1 ~ 0.5的CaTi1-x(Nb1/2Al1/2)xO3陶瓷。x射线衍射(XRD)结果表明,样品具有对称的正交晶体结构(Pbnm)。利用拉曼光谱进一步证实了这种对称性。共检测到13种拉曼模式,与XRD结果一致。样品的微观结构分析表明,样品中有孔隙,可能是由于Al的取代,具有较高的熔点。随着Al和Nb浓度的增加,相对介电常数(er)、质量因子(Q×fo)和谐振频率温度系数减小。在1650℃下烧结8 h,获得了最佳的微波介电性能,即er ~27.09, Q×fo ~17378 GHz和tf ~ -2.5 ppm/℃。

Understanding the phase formation mechanisms in self-propagating high-temperature synthesis from the thermodynamical aspect of view is important. In this study, the phase formation of the ternary system of nickel-titanium-silicon was studied by using the HSC software V6.0, and phase formation is predicted by calculating the adiabatic temperature of exothermic reaction between reagents. Then, by using X-ray diffractometer analysis, the results of the simulation were evaluated by experimental achievements. Results showed a good correlation between thermodynamical calculation and prediction with experimental. It could be concluded that the equilibrium mechanism is the dominant mechanism in phase formation in the SHS synthesis method. NiTiSi solid solution phase is obtained from the reaction between Ti5Si3 and Ni2Si and Ni.

A significant proportion of mined natural corundum (ruby and sapphire) contain fractures, which negatively affects a gemstone’s clarity and value. Over the past decades, heat treatment techniques have been developed for either fracture healing, or filling to make such gems marketable. The clarity enhancement processes are mainly based on techniques which are either not durable, as in the case of lead silicate fillers, or do not yield perfect transmittance through a fracture, as in the case of borax based fluxes. Therefore, the gemstone treatment community is actively in pursuit of better techniques for clarity enhancement in corundum. Given that application of pressure is a recent advancement in the heat treatment processes of natural sapphire, it is essential to explore the possibilities regarding different outcomes such treatments can have. In this perspective paper, we have briefly described how application of pressure during heat treatments can lead to in-situ sintering of transparent polycrystalline ceramics within the fractures of corundum, which can result in clarity enhancement. Spinel-structure based fillers can be tailored to mimic corundum in terms of tribological, chemical and optical properties. Therefore, gemstones treated with such fillers will be durable, unlike currently used glass-based filler material. We also provide a possible explanation for ghost-fissures in sapphires heated under pressure, as being a by-product of in-situ sintering process of ceramic fillers that are thermodynamically compatible with Al2O3. The prospect of transparent polycrystalline ceramics in the gem and jewelry industry opens a new field of research in this area, given that ceramic fillers can outperform currently used methods and material for clarity enhancement in gemstones. In essence, we present a novel application for sintered transparent polycrystalline ceramics.
开采的天然刚玉(红宝石和蓝宝石)中有很大一部分含有裂缝,这会对宝石的净度和价值产生负面影响。在过去的几十年里,热处理技术已经被开发出来用于骨折愈合或填充,使这些宝石能够销售。提高透明度的工艺主要基于要么不耐用的技术,如硅酸铅填料的情况,要么不能通过裂缝产生完美的透光率,如硼砂基助焊剂的情况。因此,宝石处理界正在积极寻求更好的技术来提高刚玉的净度。考虑到压力的应用是天然蓝宝石热处理工艺的最新进展,探索这种处理可能产生的不同结果的可能性是至关重要的。在这篇前瞻性的论文中,我们简要地描述了在热处理过程中施加压力如何导致透明多晶陶瓷在刚玉断裂中原位烧结,从而提高透明度。基于尖晶石结构的填料可以在摩擦学、化学和光学性能方面模仿刚玉。因此,用这种填料处理的宝石将是耐用的,不像目前使用的玻璃基填料材料。我们还提供了一种可能的解释,作为与Al2O3热相容的陶瓷填料原位烧结过程的副产品,在压力下加热蓝宝石中的幽灵裂纹。透明多晶陶瓷在宝石和珠宝行业的前景为这一领域的研究开辟了一个新的领域,因为陶瓷填料可以比目前使用的方法和材料更好地提高宝石的透明度。本质上,我们提出了一种新的应用烧结透明多晶陶瓷。

In the current work, high density polyethylene (HDPE) composites were fabricated via Friction Stir Processing (FSP). A two-phase Fe-Fe3O4 powder was used as the reinforcing agents. The extremely low cost powder was obtained from shot-blasting of as-forged low carbon steel components. X-ray diffraction (XRD) was used to phase analysis and evaluation of the purity of the as-received powder. The size distribution of the powder was determined by Laser Particle Size Analysis (LPSA). Also, Scanning Electron Microscopy (SEM) was employed to investigate the particles morphology. The processing used a cylindrical tool to impose the severe plastic deformation and material stirring in order to improve the mechanical properties and particles distribution. The tribological and mechanical properties of the fabricated samples were examined. According to the results, both the friction coefficient and specific wear rate of FSPed samples reduced remarkably. The hardness and tensile strength of the FSPed composites were higher than the FSPed HDPE samples; however, their elongations were lower.

Role of Ti3AlC2 MAX phase on characteristics of in-situ synthesized TiAl intermetallics. Part I: sintering and densification Ti3AlC2 MAX相对原位合成TiAl金属间化合物性能的影响第一部分:烧结和致密化

Five TiAl–Ti3AlC2 composite samples containing (10, 15, 20, 25 and 30 wt% Ti3AlC2 MAX phase) were prepared by spark plasma sintering technique at 900 °C for 7 min under 40 MPa. For this purpose, metallic titanium and aluminum powders (aiming at the in-situ formation of the TiAl matrix phase) were ball-milled with predetermined contents of Ti3AlC2 MAX phase, which already was synthesized using the same metallic powders as well as graphite flakes. Displacement-time-temperature variations during the heating and sintering steps, displacement rate versus temperature, displacement rate versus time, and densification behavior were studied. Two sharp changes were detected in the diagrams: the first one, ~16 min after the start of the heating process due to the melting of Al, and the second one, after ~35 min because of the sintering progression and the applied final pressure. The highest relative densities were measured for the samples doped with 20 and 25 wt% Ti3AlC2 additives. More Ti3AlC2 addition resulted in decreased relative density because of the agglomeration of MAX phase particles.
采用火花等离子烧结技术,在900℃、40 MPa、7 min条件下制备了5种Ti3AlC2复合材料样品(Ti3AlC2 MAX相含量分别为10%、15%、20%、25%和30%)。为此,金属钛和铝粉(旨在原位形成TiAl基体相)被预先确定含量的Ti3AlC2 MAX相球磨,而Ti3AlC2 MAX相已经用相同的金属粉末和石墨薄片合成。研究了加热和烧结过程中位移-温度变化、位移速率-温度变化、位移速率-时间变化以及致密化行为。在图中可以检测到两个明显的变化:第一个变化发生在加热过程开始后约16分钟,原因是铝的熔化;第二个变化发生在约35分钟后,原因是烧结过程和施加的最终压力。对于掺有20%和25% Ti3AlC2添加剂的样品,测量了最高的相对密度。Ti3AlC2添加量越大,由于MAX相颗粒的团聚,导致相对密度降低。

More Ti3AlC2 addition resulted in decreased relative density because of the agglomeration of MAX phase particles.","PeriodicalId":22113,"journal":{"name":"Synthesis and Sintering","volume":"96 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81885780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the ongoing research on photocatalysis under visible-light, it has been shown that doped or hybrid catalysts are more active than a single catalyst alone. However, problems including visible light absorption, a low quantity of energetic sites on surfaces, and rapid recombination of the photo-electron hole pair produced by light have prohibited photocatalysts from being used in a practical and widespread manner. To overcome these problems, synthesis of nanostructure hybrid catalyst using several methods has attracted much attention. Several procedures have been suggested for the preparation of photocatalysts with the desired structure and morphology. Preparation methods similar to partial modification may lead to diverse structures and qualities. In this regard, the development of efficient, low-cost photocatalysts and rapid synthesis is the most important issues that should be considered. This review discusses various methods and mechanisms that work with the modification of vanadium compounds as photocatalysts to progress their photocatalytic efficiency. In addition, the effects of synthesis temperature, solution pH and concentration on the photocatalytic performance are also described in detail.
在可见光下正在进行的光催化研究中,已经证明掺杂或杂化催化剂比单独使用单一催化剂更有活性。然而,可见光吸收、表面高能位点数量少以及光产生的光电子空穴对的快速重组等问题阻碍了光催化剂的实际和广泛应用。为了克服这些问题,采用多种方法合成纳米结构杂化催化剂引起了人们的广泛关注。提出了几种制备具有理想结构和形态的光催化剂的方法。类似于部分改性的制备方法可能导致不同的结构和质量。在这方面,开发高效、低成本和快速合成的光催化剂是最需要考虑的问题。本文综述了钒化合物光催化改性的各种方法和机理,以提高其光催化效率。此外,还详细介绍了合成温度、溶液pH和浓度对光催化性能的影响。

In this research, Cr2O3 ceramic nano-sized powder particles were prepared using ball milling and then were granulated to reach the proper size for spraying. Afterward, Cr2O3 nano-coatings were deposited by atmospheric plasma spraying (APS) process onto stainless steel substrates. To optimize APS parameters, spraying was carried out under six conditions with different parameters. Microstructures of the elemental/milled powder and coatings were characterized via a field emission scanning electron microscope (FESEM) equipped with energy-dispersive spectroscopy (EDS). In this research, Cr2O3 coatings were deposited under different spraying conditions to understand the effect of APS parameters on the splat formation, deposition efficiency, and porosities of the coatings. After parameter optimization, spraying was performed under a high deposition efficiency of 46.0±1.3%. The optimized Cr2O3 coatings showed porosity content, Knoop microhardness, and adhesive strengths of 8.7±2.2%, 823±27 HK0.2, and 49±4 MPa, respectively; making them a good candidate for industrial use.

Ab-initio study of paramagnetic defects in Mn and Cr doped transparent polycrystalline Al2O3 ceramics Mn和Cr掺杂透明多晶Al2O3陶瓷顺磁缺陷的Ab-initio研究

Birefringence is a major source of difficulty in sintering of transparent polycrystalline alumina ceramics, especially as the grain size exceeds a few hundred nanometers, which ultimately leads to complete opacity, mainly due to scattering of light. Recent studies have made it clear that by application of a strong magnetic field, alumina grains can be aligned along a particular crystallographic orientation, which minimizes scattering due to birefringence, and enhances transparency. Defects that cause spin delocalization are known to induce a paramagnetic behavior in alumina ceramics. Therefore, such defects have become a focal point of research for magnetic field assisted sintering of transparent polycrystalline alumina, in order to reduce the necessary magnetic field strength during production process. In light of recent studies on paramagnetic potentials of transition metal doped alumina, we have applied Spin Polarized Density Functional Theory (SP-DFT) calculations on manganese and chromium doped and co-doped alumina to calculate the magnetic moments, density of states and defect formation energies, which should be expected from this system of dopants, along with their interactions with oxygen vacancies. The results clearly indicate that formation of a point defect comprised of chromium and manganese positioned substitutionally at adjacent aluminum sites, in vicinity of an oxygen vacancy can induce a magnetic moment equivalent to 5 Bohr magnetons (μβ), outperforming previously reported defects. Based on this study we find it likely that chromium and manganese co-doping in alumina can further reduce the required magnetic field strength for production of transparent polycrystalline alumina.
双折射是透明多晶氧化铝陶瓷烧结困难的主要来源,特别是当晶粒尺寸超过几百纳米时,这最终导致完全不透明,主要是由于光的散射。最近的研究表明,通过施加强磁场,氧化铝颗粒可以沿着特定的晶体取向排列,从而最大限度地减少由于双折射引起的散射,并提高透明度。引起自旋离域的缺陷已知会在氧化铝陶瓷中诱发顺磁性行为。因此,这类缺陷已成为磁场辅助烧结透明多晶氧化铝的研究热点,以降低生产过程中所需的磁场强度。鉴于最近对过渡金属掺杂氧化铝的顺磁势的研究,我们应用自旋极化密度泛函理论(SP-DFT)计算了锰和铬掺杂和共掺杂氧化铝的磁矩、态密度和缺陷形成能,以及它们与氧空位的相互作用。结果清楚地表明,在氧空位附近的相邻铝位上形成由铬和锰取代组成的点缺陷,可以产生相当于5玻尔磁子(μβ)的磁矩,优于先前报道的缺陷。基于本研究,我们发现在氧化铝中铬锰共掺杂可能会进一步降低生产透明多晶氧化铝所需的磁场强度。
