摘要

对 30KhGSA 钢进行了淬火分区（Q&P）热处理后和传统淬火后的研究。对其进行了结构和 X 射线分析，并测定了机械性能。Q&P处理产生了马氏体-奥氏体结构，奥氏体保留率为10%。用 Q&P 代替传统的淬火工艺，冲击韧性提高了 3 倍，抗疲劳裂纹增长能力提高了 2 倍。在室温下长时间保温（超过一个月），Q&P 钢中的残余奥氏体含量降低到 7.5 Vol.%，与淬火后的状态相比，冲击韧性和抗裂能力降低了 1.5 倍。

Effect of Natural Aging on the Structure and Properties of Steel 30KhGSA Hardened by Quenching and Partitioning

Steel 30KhGSA is studied after a quenching and partitioning (Q&P) heat treatment and after traditional quenching. Structural and x-ray analyses are performed and mechanical properties are determined. The Q&P treatment produces a martensite-austenite structure with 10 vol.% retained austenite. The use of Q&P instead of the traditional quenching elevates the impact toughness by a factor of 3 and the resistance to fatigue crack growth by a factor of 2. A long hold at room temperature (for more than a month) reduces the content of retained austenite in the Q&P-steel to 7.5 vol.% and lowers its impact toughness and crack resistance by a factor of 1.5 as compared to the state right after the hardening.
