摘要
综述了奥氏体等温转变铸铁的最新研究成果。阐述了球墨铸铁奥氏体等温转变的最新理论及高碳奥氏体的稳定性 ,论述了化学成分及形变对奥氏体等温转变过程的影响 ,概述了奥氏体等温转变灰铸铁、蠕墨铸铁及可锻铸铁的热处理工艺特点。
Recent researches on austempered cast irons have been reviewed. The present theories of the austempering transformation and the stability of high carbon austenite in ductile cast iron have been presented. The effects of chemical and mechanical deformation on austempering transformation have been discussed. The heat treatment processes, some mechanical properties and their applications of austempered gray iron, austempered compacted iron and austempered malleable iron have been introduced.
