摘　　要：试验结果表明 ,在亚临界区加热 ,缓慢冷却 ,非调质钢 3 0Mn2V中铁素体含量增多且不出现粒状贝氏体组织 ,可使室温冲击韧性大幅度提高。The test results showed that with subcritical normalizing and low cooling rate, the ferrite volume percent increased in non\|quenched\|tempered steel 30Mn2V and there was no granular bainite in structure that result in increasing the impact toughness of steel at room temperature obviously.

关 键 词：组织 非调质钢 30Mn2V 亚温正火 冲击韧性
