摘要
本文研究了铜在 0 6NiCuCrMoNb钢中的时效硬化行为。结果表明 :0 6NiCuCrMoNb钢在时效过程中发生ε-Cu的析出硬化和淬火组织软化两个过程。时效硬化峰值温度为 4 50～ 50 0℃ ,时效时间为 2小时 ,较佳固溶温度为
The paper has studied the age-hardening behavior of Cu in 06NiCuCrMoNb steel.The results show that there are two different changes during aging.They are age-hardening and microstructure tempering (When ε-Cu was precipitare).The maximum age-hardening temperature of 06NiCuCrMoNb steel is about 450-500℃ for two hours and the best solution temperature is 850℃.
