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.
