precipitation heat treatment

The properties,such as tensile property at room temperature,hardness,electrical resistivity and SCC of 7A52 alloy by high temperature pre-precipitation treatment were tested.

通过对高温预析出处理的7A52合金在T61和自然时效状态的强度、硬度、电阻率和应力腐蚀开裂(SCC)的测试,对比分析了高温预析出对7A52合金自然时效和T61时效状态下应力腐蚀性能的影响。
