摘　　要：已获得合金的有效强化规范,即460℃淬火160℃2小时时效。热差分析和机械性能试验表明,本合金对淬火过烧温度不甚灵敏,有利于工业生产的控制。本文还对工艺过程几种不同状态进行了机械性能的比较。The regulations of effective strengthening for the alloy are defined as follows: quenching at 460℃ and ageing at 160℃ for two hours. It is shown by differential thermal analysis and mechanical property test that there occurs no overheating during quenching in the alloy and that the regulations can be easily controlled, Comparisons between mechanical properties achieved under different condition of process are made.
