‘Intrinsic Stress’, σ0, in the High-Temperature Behaviour of Metals

THE governing relation between strain η and stress σ for the behaviour of metals at temperatures above about half the melting point seems to be of the form : where E is the elastic modulus and M is a function of temperature1. The quantity σ0, which has the dimensions of stress, is a constant for a metallurgically stable material and is independent of… CONTINUE READING
