摘要
采用正交组合回归设计实验方法 ,研究了“零保温”淬火条件下 ,加热温度和回火温度对 2 0MnV钢强度和硬度的影响规律 .试验结果表明 ,淬火温度对该钢的抗拉强度和硬度有显著影响 ,适当提高淬火温度 ,2 0MnV钢“零保温”淬火的强硬性高于常规
The regularity of effect of heating temperature and tempering temperature on 20?MnV steel's hardness and strength in zero time holding quenching has been researched by the orthogonal regressive principle.The experiment results have shown that the quenching temperature has remarkable on its hardess and tensile strength.When the quenching 簦澹恚穑澹颍幔簦酰颍? is raised properly,the 20?MnV steel's strength and hardness in zero time holding quenching are higher than that of the conventional 880℃ quencging.
