摘　　要：对阀门钢５Ｃｒ２１Ｍｎ９Ｎｉ４Ｎ在１００～７００℃的变形抗力与变形温度、变形速度的相互关系进行试验研究，并通过计算机回归分析得到其变形抗力数学模型：σ＿ｓ＝９８４．１３２１５ε０．１８３８０２２ｅｘｐ（－０．０００８９１９２２Ｔ＿ｋ）ＭＰａ（复相关系数Ｒ＝０．９５９１３２９）In this paper,the relationship between deformation resistance and deformation rateand deformation temperature of 5Cr21Mn9Ni4N valve steel has been studied experimently at 100～700℃. And the mathematic model of deformation resistance is obtained by computer regressiveanalyses:σ_s=984.13215ε0.1838022exp(-0.000891922T_k)MPa(rerelationship coefficiant R=0.9591329)
