摘要

探讨了0Cr17Ni7Al不锈钢不同时效处理温度、时间对其力学性能的影响。采用电子万能试验机以及扫描电镜分析了时效后不锈钢的力学性能及断口形貌。结果表明

0Cr17Ni7Al不锈钢的最佳时效温度为410

30℃

其抗拉强度在1 977

030MPa范围内

塑性变形量为24%

且时效时间对抗拉强度影响不大;而高温时效后的塑性变形量仅为11%。0Cr17Ni7Al不锈钢在410

30℃时效后断口形貌为韧性断口

伴有大量韧窝

同时出现连续脉纹形貌

使塑性变形明显改善。

Abstract

Effects of aging temperature and time on mechanical properties of 0Cr17Ni7Al stainless steel were investigated.The mechanical properties and fracture surfaces of the 0Cr17Ni7Al stainless steel were analyzed by the electronic universal testing machine and scanning electron microscopy（SEM）.The results show the ultimately fracture strength and plastic deformation of 0Cr17Ni7Al stainless steel are in the range of 1977

030 MPa and 24%

respectively

with aging treatment at 410

30 ℃

while effects of the aging time on tensile strength of 0Cr17Ni7Al stainless steel can be ignored.However

the plastic deformation is only 11% after aging treatment at high temperature.A large number of dimples and continuous vein morphologies are observed in 0Cr17Ni7Al stainless steel with aging treatment at 410

30℃

providing apowerful support for the plastic deformation.
