The Mechanical Effects of a Dispersion of a Second Phase.

Abstract

The review of the effects of a dispersion of discrete particles on the mechanical properties of crystals considers models at two levels: (a) the continuum or quasi-continuum level and (b) the microscopic or atomistic level. The simpler continuum approach yields upper or lower bounds for the flow stress or strain rate. In many cases (e.g. work hardening) this is the best we can do at present. Other properties (e.g. the yield stress and the inhibition of diffusional creep by particles) can only be explained by microscopic models. (Author)
