Abstract

The finite-element method is used to study the effect of sand shell size on compaction and shape change during compaction of billets formed from the hot products of self-propagating high-temperature synthesis. The extreme nature of the change in billet density in relation to shell thickness that governs its reserve of compressibility is established. In order to make high-density billets it is necessary that shell compressibility reserve is higher than that of the synthesis products. With decrease in shell radial dimensions there is distortion of billet shape due to a nonuniform stress-strained state close to the side surface of the tool with external friction.
