| 摘 要： | 利用光学显微镜、扫描电镜等手段系统研究了 AISI 8630锻件不同热处理工艺对试验样品的力学性能和组织的影响,结果表明:水冷淬火后锻件心部获得完全马氏体或大部分马氏体组织,回火后获得索氏体组织,可以满足锻件的性能要求.分析影响材料力学性能的原因可能是碳化物的分布形态和形貌,可为实际产品制定热处理工艺提供参考数据.

| Abstract: | By means of optical microscope and scanning electron microscope,the effects of different heat treatment processes on the mechanical properties and microstructure of AISI 8630 forgings have been systematically studied.The results show that the core of forgings obtain complete martensite or most of the martensite structure after water cooling quenching,and the sorbite structure has been obtained after tempering,which could meet the performance requirements of forgings.The influence of mechanical properties of materials may be caused by the distribution and morphology of carbide,which can provide reference data for the formulation of heat treatment process for actual products. |
