The addition of Fe to Cr-Cr{sub 2}Ta eutectic alloys increased ambient fracture toughness from a maximum of 12-14 to 18-21MPa m{sup 1/2}. The elevated-temperature yield strength was depressed, but still reached >250 MPa at 1000 C. The Fe additions also resulted in a potentially beneficial change in oxidation mechanism from Cr{sub 2}N subscale formation to internal oxidation.
