Self-propagating high-temperature synthesis under the combined action of pressure and shear

Abstract

A study was made of the role of high-temperature shear deformation in the processes of combustion and structuring of titanium carbide, which lead to changes in the grain size and morphology and in the quality of the end product. It was shown that, by applying shear loads to the as yet unformed material, the structure and morphology of the obtained powder can be affected. Shear deformation during self-propagating high-temperature synthesis results in an almost 100% yield of a powder with a particle size of less than 400 μm.
