摘　　要：研究了机械传动轴用40Cr材料在双向应力环境下低载强化特性。结果表明,拥有强化作用的载荷区间是39.2-51.0 N·m,强化次数区间是1-40万次。并且,20万的强化次数下,当强化载荷达到44.10 N·m时的强化作用最佳。The low-load strengthen characteristics of the material 40 Cr used in mechanical transmission shaft under biaxial stress environment was investigated. The results show that the load range with strengthen effect is 39.2-51.0 N·m, and strengthen times range is 10 000-400 000. The strengthen effect is optimal when the strengthen load is 44.10 N·m under the strengthen times of 200 000.
