作者应用新的合金设计思想,研制了一类新型高碳低合金超高强度钢。经适当热处理,获得贝氏体铁素体板条与奥氏体薄膜交替排列的奥氏体-贝氏体双相组织。文中研究了钢的组织、力学性能及其与转变温度的关系。
The authors apply a new alloy design ideas, developed a new type of high-carbon low-alloy ultra-high strength steel. After appropriate heat treatment, bainitic ferrite laths and austenite films are alternately arranged in the austenite-bainite duplex structure. The text studied the microstructure and mechanical properties of steel and its relationship with the transition temperature.
