介绍了两种模拟增材制造(AM)材料微观结构的方法。第一种方法依赖于金属增材制造过程中微观结构演变的数学描述,同时考虑到复杂的物理过程。数值解是基于模拟AM热过程的有限差分法和描述晶粒生长的元胞自动机方法的结合。另一种方法是使用分步填充方法,通过颗粒的几何特征快速生成类似于增材制造的人工3D微结构。
Two approaches to simulating microstructures typical of additively manufactured (AM) materials are presented. First approach relies on the mathematical description of the microstructure evolution during metal AM process, taking into account complex physical processes involved. The numerical solution is based on a combination of the finite difference method for modeling AM thermal processes and the cellular automata method for describing the grain growth. The other approach provides fast generation of artificial 3D microstructures similar to those produced by AM by geometrical characteristics of grains, using the step-by-step packing method.
