Formation of gradient structures in cemented carbides

Some aspects of gradient structure development in cemented carbides at micr oscopic and submicroscopic levels are considered. The gradient structures a re shown to develop mainly due to the nonequilibrium process of the liquid phase mass transfer in cemented carbides. Particular emphasis is placed on the theoretical and experimental description of the process of treatment wi th metal melts which allows the gradient structures at microscopic and subm icroscopic levels to be obtained.
