MORPHOLOGY AND SIMULATION OF SOLID-STATE ROUNDING PROCESS

A two dimensional rounding process model, including morphological anal yses of grain form and calculation of flux of surface diffusion driven by difference of curvature, is developed and solved numerically. Resu lts from simplified model runs, intended to illustrate the shape depen dence of rounding rate, are presented. The method for evaluation of th e morphological feature of grains during rounding and the method for e stimation of actual flux from the morphological analysis of experiment al products are discussed.
