Abstract

This paper presents results from mathematical modeling of plastic deformation of heterophase alloys with noncoherent particles under creep flow conditions. Creep curves are plotted for a range of moderate temperatures. Influence of scale characteristics of the strengthening phase on the creep curves has been studied. It has been shown that larger deformation is attained when the volume ratio is lower and the particle size is larger. Dependencies of deformation defect subsystems corresponding to the creep curves have been calculated.
