摘要
选择性激光熔化技术具有一次成形、节省原材料、可成形任意复杂结构工件及性能优良等特点,是17-4PH不锈钢成形研究的新方向。本文综述了近几年选择性激光熔化制备17-4PH不锈钢研究现状,包括工艺参数对17-4PH不锈钢性能的影响,热处理和热等静压对17-4PH不锈钢力学性能的改善,不同成形方式和不同后处理17-4PH不锈钢的显微组织变化,以及在选择性激光熔化成形17-4PH不锈钢过程中出现的问题和发展趋势。
Selective laser melting technology(SLM)is a new direction in the forming research of the 17-4PH stainless steels because of the advantages of one-time forming,raw material saving,arbitrary complex structure workpiece forming,and excellent performance.The research status of the 17-4PH stainless steels prepared by SLM in recent years was reviewed in this paper,including the effect of process parameters on the properties of the 17-4PH stainless steels,the improvement on the mechanical properties of the17-4PH stainless steels by heat treatment and hot isostatic pressing(HIP),the microstructure changes of the 17-4PH stainless steels treated by the different forming ways and the different post-treatments,and the problems and development trend of the 17-4PH stainless steels by SLM.
