Additive Manufacturing (AM) technology produces three-dimensional components in a layer-by-layer fashion and offers numerous advantages over conventional manufacturing processes. Driven by the growing needs of diverse industrial sectors, this technology has seen significant advances on both scientific and engineering fronts. Fusion-based processes are the mainstream techniques for AM of metallic materials. As the metals go through melting and solidification during the printing processes, the final microstructure and hence the properties of the printed components are highly sensitive to the printing conditions and can be very different from those of the feedstock. It is critical to understand the process-microstructure-property relationship for the accelerated optimization of the processing conditions and certification of the printed components. While experimentation has been used widely to acquire a mechanistic understanding of this subject matter, numerical modeling has become increasingly helpful in achieving the same purpose.

用于预测基于融合的金属增材制造中工艺-微观结构-性能关系的多物理场建模框架

增材制造 (AM) 技术以逐层方式生产三维组件，与传统制造工艺相比具有众多优势。在不同工业部门不断增长的需求的推动下，这项技术在科学和工程领域都取得了重大进展。基于熔融的工艺是金属材料增材制造的主流技术。由于金属在打印过程中经历熔化和凝固，因此打印部件的最终微观结构和性能对打印条件高度敏感，并且可能与原料的显微结构非常不同。了解工艺-微观结构-性能关系对于加速优化加工条件和打印组件的认证至关重要。虽然实验已被广泛用于获得对这一主题的机械理解，但数值建模在实现相同目的方面变得越来越有帮助。
