摘　　要：采用热力学计算,分析了试验钢各主要合金含量对组织含量和力学性能的影响规律。结果表明,在一定范围内,Mn、Mo、Cr、Ni等元素可以提高试验钢的力学性能,质量分数0.3%的Cr元素,可以使其硬度可达到43.6HRC,屈服强度和抗拉强度均可显著提高。This paper employs thermodynamic calculations to analyze how the major alloy contents influence the microstructure and mechanical properties of the experimental steel.The findings demonstrate that,within a specific range,elements like Mn,Mo,Cr,and Ni have the capability to enhance the mechanical properties of experimental steel.For instance,incorporating 0.3%mass fraction of Cr,along with other elements,noticeably enhances the hardness of the experimental steel,resulting in a hardness level of 43.6HRC,while also improving its yield strength and tensile strength.
