Alloy elements can either enhance or inhibit temper embrittlement in alloy steels. The enhancement can occur by increasing the segregation of impurities through synergistic cosegregation by lowering the activity of carbon (which strengthens grain boundaries), by imparting resistance to softening during tempering, or by actually decreasing grain boundary cohesion in a manner similar to impurities. The inhibition of embrittlement occurs by impurity scavenging, by segregation and a concomitant increase in grain boundary strength, or by an increase in the inherent toughness of the ferritic matrix. These factors will be reviewed in the light of recently published reports and new experimental findings.
