Abstract
The addition of Fe to Cr-Cr2Ta eutectic alloys increased ambient fracture toughness from a maximum of 12-14 to 18-21 MPa m1/2. 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 Cr2N subscale formation to internal oxidation.
