It was shown in the previous report that the toughness of as-solidified steel was significantly influenced by the sulfur-segregation through the Fe-C peritection reaction. For this reason, 0.1% of carbon content is a critical value for weld metal toughness. In this report, the influence of the peritectic reaction of the Fe-Ni-C ternary system on the toughness and sulfur-microsegregation of as-solidified steel were investigated. It was concluded that this ternary peritectic reaction had also the critical significance for the toughness of as-solidified steel and the nickel and carbon content of steel weld metal shoule be controlled under this ternary peritectic reaction, i.e. so as to solidify into only δ phase to get higher toughness.
