摘要
在优选化学成分的基础上 ,研究了等温淬火 (90 0℃× 2h/3 2 5℃× 1 .5h)对灰铸铁、蠕墨铸铁及球墨铸铁组织和性能的影响。结果表明 ,经此工艺处理后 ,三种铸铁的力学性能显著提高。
Based on optimum selecting chemical composition,the influences of austempering on microstructres and properties of gray cast iron,compacted graphite cast iron and ductile cast iron were investigated.The results showed that dynamical properties of cast iron markedly increased by austempering.
