摘要
研究了低碳奥氏体—马氏体双相不锈钢在不同回火温度下硬度变化规律。根据回火硬度的变化,分析了回火过程中组织转变及逆转变奥氏体对回火硬度的影响。同时在一次回火的基础上进行了二次回火处理,比较一次回火和二次回火的硬度变化规律,确定了低碳奥氏体—马氏体双相不锈钢的最佳热处理工艺。
This paper has studied hardness changing law of low carbon austenite-martensite double phases stainless steel at different tempering temperatures. According to tempering hardness change, we analyze the effect of the change of microstructure and adverse transformation austenite on the temper hardness. At the same time, on the basis of one time tempering we have done twice tempering freatment Comparing their hardness changing law, we determine low carbon austenite-martensite double phases stainless steel 憇 best technology of heat treatment.
