摘要
研究了42CrMo 钢得到混合组织(M+B+P_细+F)的热处理工艺及在相同硬度条件下混合组织与单一回火索氏体组织的接触疲劳性能。结果表明,混合组织的接触疲劳寿命(N_o、N_f)高于单一回火索氏体组织。
Technology of heat treatment of mixed structure in 42CrMo steel,contact fatigue propertiesof mixed structure and single tempered sorbite structure are compared under the same bardness.Ex-perimental results show that contact fatigue life of mixed structure is better than that of single tem-pered sorbite.
