摘要
研究了不同热处理工艺对沉淀硬化不锈钢S45000力学性能的影响。结果表明:随着时效温度的升高,强度和硬度下降,-45℃冲击韧性增加;经过二次时效处理,强度和硬度下降,-45℃冲击韧性增加。
The eftect ot dltterent neat treatment, ening stainless steel S45000 was studied. The results showed that the strength and hardness of S45000 steel decreased and impact property at -45 ℃increased with the aging temperature increasing. The strength and hardness of S45000 steel decreased and impact property at - 45 ℃ increased after twice aging treatment.
