摘　　要：对GCr15钢进行不同的热处理工艺试验,以获得不同级别的网状碳化物,网状碳化物对冲击性能的影响研究表明:网状碳化物级别升高,冲击性能下降;还研究了退火态与淬回火态网状碳化物之间的关系。The different heat treatment technology experiments are conduced for steel GCr15 to obtain different level of network carbide and demonstrate its effect on impact property.The results show that the impact property is decreased with the increase of network carbide level.The relation between carbide in annealed and quenched steels is also studied.

关 键 词：滚动轴承 GCR15钢 网状碳化物 冲击性能
