基于质量分析拟合曲线优化15-5PH沉淀硬化不锈钢的时效温度

Optimization of aging temperature of 15-5PH precipitation hardened stainless steel based on quality analysis fitting curves

采用一款常用的质量分析软件,对15-5PH沉淀硬化不锈钢不同时效温度下的硬度和抗拉强度试验数据做了拟合分析,获得了同时满足15-5PH沉淀硬化不锈钢时效硬度和抗拉强度要求的时效温度,确定了热处理制度,缩短了工艺试验周期,满足了零件加工需求。

Using a commonly used quality analysis software,the hardness and tensile strength test data of 15-5PH precipitation hardened stainless steel aged at different temperatures were fitted and analyzed.An aging temperature is obtained to satisfy concurrently the requirements of hardness and tensile strength of the 15-5PH precipitation hardened stainless steel,the heat treatment system is determined,the process testing cycle is shortened and the machining requirements of parts are met.
