Formation of gradient structures in cemented carbides

摘要

Some aspects of gradient structure development in cemented carbides at microscopic and submicroscopic levels are considered. The gradient structures are shown to develop mainly due to the non-equilibrium 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 with metal melts which allows the gradient structures at microscopic and submicroscopic levels to be obtained.
