摘要
本文研究了热作模具钢4Cr5MoV1Si在热变形过程中碳化物的动态析出行为。TEM分析认为,动态析出的碳化物主要为Mo_2C和VC。碳化物的定量分析表明:随着固溶于基体中碳化物形成元素含量的降低,动态析出的碳化物减少。
Dynamic precipitation of carbide in hot work tool steel 4CrSMoV1Si during hot defomation are investisated in this paper. Two kinds of dynamic precipitation carbide4 M_2C and MC were observed in this steel. It is founl that anount of dynamic p(?)ecipitation carbide decreases with deoreasing the content of carbide formei in matrix,
