【摘要】 在对影响轴承钢疲劳寿命的夹杂物分析的基础上 ,采用钡合金对轴承钢进行脱氧和夹杂物的变性处理。处理后的轴承钢的疲劳寿命比相同含氧量的铝终脱氧钢提高 6 3.5 5 % ,且疲劳寿命的稳定性优于铝终脱氧钢。更多还原

【Abstract】 Synopsis Based on the analysis of effect of various inclusions on fatigue life of bearing steel, this paper introduces the results of deoxidation and inclusions modification with adding barium alloy into the steel. The fatigue life of treated steel with barium alloy was 63.55?% higher than that of Al killed steel with same oxygen content. And the stability of fatigue life of the barium alloy-treated steel was higher than Al killed steel.更多还原
