摘要
研究了淬火20CrllMoVNbNB钢在室温-750℃不同温度回火0.5—100h后的硬度相析出变化,析出相中合金元素含量变化以及回火激活能等,证明在低于400℃时,该钢的回火过程受C原子在α-Fe中扩散所控制;在高于400℃时,回火过程受合金元素Cr(以及Mo,V)
Studies were made of the effect of tempering varied at temperature rangedfrom 25 to 750℃ for 0.5 to 100 h on the changes of measured hardness, precipitated phaseand its alloying elements content as well as the activation energy of tempering for quenchedsteel 20Cr11MoVNbNB. Tempering of the steel below 400℃ may be controlled by diffusionof C atoms in α-Fe, and over 400℃, by diffusion of Cr, also Mo or V, in α-Fe
