摘要
该文用彩色金相技术显示了奥氏体—贝氏体球墨铸铁中未转变奥氏体区的组织,用定量金相研究了等温淬火温度和时间对未转变奥氏体区的影响,讨论了未转变奥氏体区对奥—贝球铁性能的影响。
The microstructure of untransformed austenite areas inaustenititc-baintic ductile iron is revealed by colour metallography.The effect of austempering temperature and austempering time on un-transformed austenite areas is studied by quantitative metallography.The influence of untransformed austenite areas on the properties ofaustenitic-bainitic ductile iron is discussed.
