твердий сплав

On the base of the results determined by using modern physical material science methods scientific principles referred to relationships of structure, phase composition, physical and mechanical properties formation of frame metal-ceramic composites based on tungsten carbide with a multicomponent high-entropy alloy (HEA) binder during high-speed electron-beam and induction sintering has been developed for the first time and will play an important role in deepening the understanding of the processes of structure formation in dispersed heterogeneous systems.

The development is devoted to high-speed electron-beam sintering of samples from metal and metal-ceramic materials based on refractory compounds. The basic laws of structure formation in the conditions of electron-beam sintering of metal and metal ceramic materials are established. Computer simulation methods have been used to study the effect of porosity and porous structure of samples sintered under electron-beam sintering conditions on their temperature field and thermal conductivity.
