超音速微粒轰击后40Cr钢表面的组织与性能
Surface Microstructure and Properties of 40Cr Steel Treated by Supersonic Particles Bombarding
摘 要
采用超音速微粒轰击技术对退火态40Cr钢进行表面处理,利用显微硬度仪、光学显微镜和透射电子显微镜对材料表层进行观察和分析.结果表明:材料表面形成厚度60 μm的变形层,硬度在距表面一定距离处达到最高(530 HV);在距离表面50~60 μm范围内,铁素体中形成大量晶界,将铁素体晶粒分割细化;而此处的珠光体中渗碳体发生强烈弯折但没有断裂,表明渗碳体在这种情况下可以发生塑性变形.

Abstract
Annealed 40Cr steel was treated by supersonic particles bombarding (SSPB).Microhardness tester,optical microscope and transmission electron microscope were used to analyze surface microstructure of the steel.The results showed that a 60 μm deep deformed layer was formed on the steel surface,and the microhardness reached the highest of 530 HV at a certain distance to the surface.Plenty of grain boundaries were formed in the ferrite at the distance range about 50-60 μm to the surface,and the ferrite was divided into submicro grains.At the same distance range,cementite in the pearlite was curved severely but not fractured,which indicated that the cementite was able to be defomed plastically.
