| Abstract: | The effect of fining treatment of carbide and grain on bearing steels fatigue life was investigated. The results showed that fining the grain of the bearing steel can decrease its fatigue crack, growth rate,and fining the grain and the carbide at the same time can make its fatigue crack growth rate more slowly than fining the grain only. |
