摘    要:采用金相显微镜﹑扫描电镜和冲击试验研究了热处理对经970℃15%热变形的低铬耐磨铸铁冲击韧度的影响。结果表明,15%热变形低铬耐磨铸铁经970℃保温3 h正火后,可获得较高的冲击韧度,但其硬度变化不大。

关 键 词:低铬耐磨铸铁  热变形  热处理  冲击韧度

Abstract:Effect of heat treatment on impact toughness of low chromium wear resistant cast iron hot deformed by 15% at 970 ℃ was investigated by means of optical microscope,SEM and impact test.The results show that impact toughness of the cast iron was improved through normalization at 970 ℃ for 3 h with little change in hardness.
Keywords:low chromium wear resistant cast iron  hot deformation  heat treatment  impact toughness
