Abstract
Fe-P alloys containing up to 0. 67 wt% phosphorus show intergranular fracture by an impact test after quenching from 1,073 K. Additions of up to 0. 1 wt% of carbon prevents fracture caused by the grain boundary segregation of phosphorus and lowers the ductile-brittle transition temperature (DBTT) due to segregation of carbon. Aging at 873 K of a quenched specimen with 0. 52% P and 0. 0008% C lowers DBTT and increases the degree of grain boundary segregation of carbon.
