Abstract

This paper considers to what extent the second-phase volume fraction in superplastic binary alloys affect the matrix grain size stability during deformation and, through it, the flow stress at constant temperature and strain rate. It is shown for five different superplastic binary alloy systems, that at constant temperature and strain rate the flow stress will increase with the deviation of the second-phase volume fraction in the alloys from that required for maximum matrix grain size stability. A new parameter (Z) which quantifies these deviations has been introduced in this paper. The possible errors in determining the pertinent parameters in the rate equation for superplastic flow by testing alloys withZ is discussed.
