摘要
残余应力是导致选择性激光熔化(SLM)制造金属构件失效的关键因素之一。介绍了SLM制造过程中残余应力的产生机制和检测方法,综述了SLM工艺参数对残余应力的影响,展望了SLM制造构件残余应力研究的未来方向。
Residual stress is one of the key factors leading to the failure of metal components manufactured by selective laser melting(SLM).The generation mechanism and the testing methods of residual stress during SLM manufacturing are described;the influence of SLM process parameters on residual stress is summarized;the future direction of residual stress research of SLM manufactured components is prospected.
