摘　　要：对GCr15SiMo钢与GCr15SiMn钢的接触疲劳寿命进行了对比试验,高淬透性轴承钢GCr15SiMo的疲劳寿命(L_(10)、L_(50))分别是GCr15SiMn钢的疲劳寿命(L_(10)、L_(50))的1.73倍和1.68倍;初步讨论了合金元素Mo、Si提高轴承钢疲劳寿命的作用。The Contact Fatigue lives for GCr15SiMo and GCr15SiMn steel have been examined. The L_(10) and L_(50) of bearing steel GCr15SiMo with high hardenability are 1.73 and 1.68 times that of GCr15SiMn steel respectively. The available effects of bearing steel were discussed tentatively.
