Abstract The grain boundary network of WC in WC-Co is important, as cracks often travel intergranularly. This motivates the present work, where we experimentally measure fracture energy Σ2 twist boundaries between crystals using a double cantilever beam opened with wedge under displacement control WC-10wt%Co sample. this type was compared cleaving { $$10\overline{1}0$$ <mml:math xmlns:mml="http...

High-entropy alloys (HEAs) hold promise for achieving excellence performance due to unconventional composition and structure. In this paper, the effect of FeCoCrNiAl HEAs as binder instead Co on microstructure WC cemented carbide was investigated. The isothermal oxidation resistance WC-HEAs carbides with 6, 10, 15 % studies at 700, 800, 900 1000 °C. results revealed that microstrcture dense, av...
