摘　　要：对不同变形量的中铬半钢碳化物的形态及冲击疲劳性能进行了探讨,结果表明:变形量为0～40%时,变形量越大,碳化物破碎越充分,冲击疲劳性能越好.The phase and impact fatigue strength of medium-chromium semi-steel with different extent of deformation are researched. It is showed from the result that the bigger the deformation within 0 to 40 percent, the fuller the carbide got broken and the better the impact fatigue strength.

关 键 词：热变形 中铬半钢 碳化物形态 冲击疲劳性能
