摘要: 本文研究了一種新型的高硬度(HRC>58),高韌性(a_k ≥ 40J/cm²)的結構鋼的化學成分及熱處理對沖擊韌性的影響,實驗結果表明,微量鈣對改善鋼在淬火-低溫回火態的沖擊韌性有重要作用,鉻含量及銅/硅比對沖擊韌性也有一定的影響。

Abstract: The effects of chemical composition and heat-treatment on the impact toughness of a new type of micro-calcium steel with high-hardness (HRC> 58) and high-toughness (a_k> 40J/cm²) have been investigated. The results show that the micro-calcium play an important role in the improving of impact toughness of quened-tempered steels. The impact toughness of steels were also controlled by the content of chromium and the ratio of copper/silicon in steels.
