本文研究了30CrMnSiNi2A钢等温淬火获得马氏体和贝氏体组织与力学性能的关系。试验结果表明:采用适当的等温淬火来控制马氏体和贝氏体的相对含量,可显著提高该钢的强韧性,对提高飞机的可靠性有重要的实际意义。
In this paper, the relationship between martensite and bainite microstructure and mechanical properties of 30CrMnSiNi2A steel obtained by isothermal quenching was studied. The test results show that using suitable isothermal quenching to control the relative content of martensite and bainite can significantly improve the toughness of the steel and has important practical significance for improving the reliability of the aircraft.
