摘要
叙述了高碳铬轴承钢中Mn、Si、Cr、Mo和Al含量及热处理工艺包括马氏体淬火-回火,贝氏体等温淬火、贝氏体-马氏体和马氏体-贝氏体淬火以及纳米贝氏体钢的研究进展。近10年发展的高强度、高塑性和高韧性的纳米贝氏体钢,因其由纳米尺寸的超细贝氏体铁素体板条和板条间富碳的残余奥氏体薄膜组成的特殊组织结构导致其在耐磨和接触疲劳性能方面也具有优越性,该纳米贝氏体轴承钢有良好的应用前景。
The progress of research on Mn,Si,Cr,Mo and Al content in high carbon chromium bearing steel,and heat treatment process including martensite quenching-tempering,bainite austempering,bainite-martensite and martensitebainite quenching,as well as nanometer-structured bainite steel for bearing are presented in this article.The nano-structured bainite with high strength,high plasticity and high impact toughness is developed in recent decade,the steel with special structure-nanometer ultra fine bainite ferrite lath and carbon-rich residual austenite film in steel has excellent wearing and contact fatigue properties,so the nano-bainite bearing steel has better application prospect.
