奥氏体混晶对钢的力学性能的影响

The Effect of Mixed Austenitic Grain on Mechanical Properties of Steel

文章采用不同的热处理规范(改变加热温度和加热速度),使钢具有不同的晶粒度(细晶、混晶和粗晶),进行了拉伸试验和系列冲击试验,探讨了混晶对钢的力学性能的影响。

Based on the test results of tensile and impact strength,the paper discusses the effect of mixed grain on mechanical properties.The various grain sizes are obtained with various standards of heat treatment.
