Effect of densification technology on the microstructure and mechanical properties of high-entropy (Ti, Zr, Hf, Nb, Ta)C ceramic-based cermets

Open Ceramics
High-entropy ceramic-based cermets represent a new and promising direction in improving the mechanical properties of conventional hardmetals through the formation of complex microstructures during synthesis. This has been systematically studied in two Co-

Sintering of TaC-Ni and TaC-Ni-Mo Cermets and Observetion on their Microstructures [PDF]

, 1989
TaC-Ni and TaC-Ni-Mo cermets were sintered at 1150～1400℃ in a vacuum of 5×10^ Torr for 1hr. The effect of addition of molybdenum on the sinterability and the microstructure of TaC-base cermets were studied by measurments of relative density and micro ...
