激光选区熔化工艺过程数值模拟的国内外研究现状
Research Status of Numerical Simulation of Selective Laser Melting Process at Home and Abroad
摘要
Abstract
Selective Laser Melting (SLM) forms metal parts with high-brightness laser through melting powder layer by layer, which can quickly manufacture fine parts with any complex structure compared to traditional processing technology. The SLM involves multi-scale, multi-influencing factors, multidisciplinary and other complex physical and chemical metallurgical processes, which are difficult to observe the microscopic physical phenomena directly by using of the traditional experimental methods. For long process development cycle and high material cost, it is urgent to develop cross-scale simulation tools to reveal the related mechanism during the process and reduce the test cycle and cost. In this paper, the research status of numerical simulation of metal SLM at home and abroad is reviewed from four aspects:macroscopic temperature field, bath pool dynamics, molten pool solidification behavior and residual stress and deformation.关键词
