Abstract

Additive Manufacturing (AM) using Selective Laser Melting (SLM) has gained significant prominence across various industries involved in stainless steel part manufacturing. Selective Laser Melting makes it possible to manufacture parts with very complex geometry and with remarkable mechanical and physicochemical properties by controlling the microstructure via the appropriate choice of process parameters. This study presents a comprehensive literature review aiming to provide the scientific and technical communities with an overview of existing knowledge and experimental data regarding the effects of Selective Laser Melting parameters and conditions on the microstructure and mechanical properties of stainless-steel parts. The objective is to highlight the impact of various factors, such as process parameters, building atmosphere, post-heat treatments and initial powder characteristics on phase transformation, porosity and microcracks formation, microstructure evolution and mechanical properties of SLMed stainless steels. Additionally, the integration of emerging Smart Additive Manufacturing (SAM) requires experimental databases, properties prediction and processing parameters optimization to enhance the entire process spanning from design to final product.

不锈钢的选择性激光熔化:工艺、显微组织、力学性能和后处理的综述

使用选择性激光熔化(SLM)的增材制造(AM)在涉及不锈钢零件制造的各个行业中获得了显著的突出地位。通过选择合适的工艺参数来控制微结构，可以制造出几何形状非常复杂、机械和物理化学性能优异的零件。本研究提供了一个全面的文献综述，旨在为科学界和技术界提供关于选择性激光熔化参数和条件对不锈钢零件微观结构和力学性能影响的现有知识和实验数据的概述。目的是强调工艺参数、制造气氛、后处理和初始粉末特性等各种因素对SLMed不锈钢相变、孔隙率和微裂纹形成、显微组织演变和力学性能的影响。此外，新兴的智能增材制造(SAM)的集成需要实验数据库、性能预测和加工参数优化，以增强从设计到最终产品的整个过程。

期刊介绍： The Journal publishes and disseminates original research in the field of material forming. The research should constitute major achievements in the understanding, modeling or simulation of material forming processes. In this respect ‘forming’ implies a deliberate deformation of material. The journal establishes a platform of communication between engineers and scientists, covering all forming processes, including sheet forming, bulk forming, powder forming, forming in near-melt conditions (injection moulding, thixoforming, film blowing etc.), micro-forming, hydro-forming, thermo-forming, incremental forming etc. Other manufacturing technologies like machining and cutting can be included if the focus of the work is on plastic deformations. All materials (metals, ceramics, polymers, composites, glass, wood, fibre reinforced materials, materials in food processing, biomaterials, nano-materials, shape memory alloys etc.) and approaches (micro-macro modelling, thermo-mechanical modelling, numerical simulation including new and advanced numerical strategies, experimental analysis, inverse analysis, model identification, optimization, design and control of forming tools and machines, wear and friction, mechanical behavior and formability of materials etc.) are concerned.
