Abstract
The features of VK5 grade WC-Co hard metal sintering have been studied in using tungsten carbide powder as feed stock, which are produced by self- propagating high-temperature synthesis. The physicochemical processes during sintering of hard metals are found to be similar to sintering process- es of standard alloys from traditional tungsten carbide powders. Produced in the present work, hard metal has high hardness, strength, and crack growth resistance being characteristic for quasi-nanocrystalline materials.
