Abstract

Abstract The stress-strain curves of the Al-Zn-Mg alloys investigated consisted of a linear and a parabolic part. The slope of the linear part, unlike that of the parabolic part, was found to be fairly independent of heat treatment, testing temperature and strain rate. The fracture stress of the samples is always smaller than what might be expected on the basis of the classical stability criterion, and this is caused by micro-crack formation at grain boundaries.
