摘要
作者研制的新型高碳硅锰低合金超高强度钢,经280～360℃等温处理,获得一种新型贝氏体组织——板条束状过饱和铁素体与薄膜状富碳奥氏体交替排列的奥氏体—贝氏体双相组织。本文从组织结构特征及转变温度等方面对新型贝氏体与常见的贝氏体组织进行了分析对比,探讨了钢的化学成分及转变温度对贝氏体组织结构的影响。
The authors have obtained a new bainite structure in a ultra-high strength low alloy (Si, Mn) steel with high carbon content after isothermal treatment at 280-360℃.The new structure is a dual phase structure of austenite and bainite, which are arranged alternatively in the form of oversaturated lath ferrite and thin film austenite rich in carbon.This paper analysed and compared the new bainite structure with the conventional bainite structure in the aspects of structural characteristics and transformation temperatures, and discussed the effects of composition and transformation temperature on the bainite structure.
