A study was carried out of the influence of periodic overheats of 2-minute duration to temperatures of 1,650, 1,800, 1,900, and 2,000 degrees F on the creep-rupture properties of M-252 alloy at 1,500 degrees F. The conditions of the experiments had been selected to provide basic information applicable to estimation of the effects of overheating on creep-rupture performance of gas-turbine parts. The overheats were conducted both with the stress removed during overheating and with stress present.
