The effect of austenitizing temperature on segregation of impurities along grain boundaries in steel 4330M has been examined by AES.The impurity segregation was computed quantitatively.Results showed that the quantity of impurity segregation changed with the austenitizing temperature.The limitation of the McLean′s expression for equilibrium segrega- tion was discussed.

用Auger谱仪研究了奥氏体化温度对4330M钢晶界上杂质偏聚的影响,并对偏聚量进行了定量计算。结果表明:奥氏体化温度不同,杂质偏聚量也不同,指出了McLean平衡偏聚理论关系式 C_g=AC_0exp[Q/RT]的局限性
