Abstract:

The object of this investigation was to determine if a parameter derived rom a mechanical-chemical equation of state could be used to characterize rupture stresses of alloys previously reported not to have been amenable to analysis with good accuracy by other formulas. Stress-rupture data for Nimonic 80A and Monel were analyzed by making calculations on assumed values of a concentration parameter. A dataplotter was used to draw master rupture curves, and a complete set was obtained in decade intervals. It is concluded that a second-order form of the mechanical-chemical equation of state K T22.78 log at2 has been found capable of characterizing Nimonic 80A and Monel, two alloys previously reported not to have been analyzable by other parameters.
