本文利用相关分析法研究了 B 级铸钢的低温冲击韧性与 C,Mn 含量的关系。列出了低温冲击韧性和 C、Mn 之间的多重回归方程式,同时还找出了其硬度(HB)和塑性(δ)之间的关系式。
In this paper, the correlation analysis method was used to study the relationship between the low temperature impact toughness and the content of C and Mn in B grade cast steel. The multiple regression equations between low temperature impact toughness and C, Mn are listed, and the relationship between hardness (HB) and plasticity (δ) is also found.
