The addition of Fe to Cr and to oxide dispersion ductilized Cr alloys modified, but did not eliminate subscale internal nitridation on oxidation in air. The addition of 45 wt.% Fe increased the room-temperature tensile yield strength of Cr-6MgO from {approx}225 MPa to {approx}650 MPa, while still exhibiting 1--1.5% tensile elongation.
