The Influence of Sintering Temperature of Reactive Sintered (Ti, Mo)C-Ni Cermets

Marek Jõeleht

Abstract


Titanium-molybdenum carbide nickel cermets ((Ti, Mo)C-Ni) were produced using high energy milling and reactive sintering process. Compared to conventional TiC-NiMo cermet sintering the parameters for reactive sintered cermets vary since additional processes are present such as carbide synthesis. Therefore, it is essential to acquire information about the suitable sintering regime for reactive sintered cermets. One of the key parameters is the final sintering temperature when the liquid binder Ni forms the final matrix and vacancies inside the material are removed. The influence of the final sintering temperature is analyzed by scanning electron microscopy. Mechanical properties of the material are characterized by transverse rupture strength, hardness and fracture toughness.
