摘要

评述了超高强度钢中二次硬化现象的基本特征,M2C析出热力学、晶体学、动力学和机理等研究现状。研究证明,在位错上单独形核、共格沉淀的介稳定相M2C是一种可用的强化相。M2C比其他稳定碳化物具有更高形核驱动力和聚集抗力,Co提高这一驱动力和形核率。Mo有效增加M2C点阵参数和聚集抗力。

Abstract

Studying development on the thermaldynamics,crystallology,kinetic stability and strengthening mechanism for precipitation of M2C carbide in ultrahigh strength steels has been evaluated. Investigation results show that M2C, nucleating on dislocation and coherent precipitating, can be used for strengthening phase although not in the equilibrium state. The driving force to nucleate and coarsening resistance for M2C is greater than any other carbides. Furthermore Co causes the markedly increase in the driving force to nucleate and nucleating coefficient for M2C. Mocauses the largest lattice parameter and enhances coarsening resistence for M2C.
