The high-temperature creep behaviour of an Fe–Al–Zr alloy strengthened by intermetallic precipitates

The creep behaviour of an Fe–Al–Zr alloy has been examined at 700 °C and compared with the behaviour of an Fe–Al–B alloy, as well as with previously reported creep data. The Zr-containing alloy is strengthened by the formation of Fe–Zr intermetallic precipitates during high-temperature exposure, which makes this alloy about as strong under such creep conditions as any iron aluminide previously examined.
