|Abstract:||The thermodynamics of the various events occurring during heating to liquid phase sintering temperatures of powder compacts of TiC- and Ti(C,N)-based cermets has been investigated. The results show that via a series of dissolution, solute repartitioning and mixed rim formation reactions, Mo 2C can not only help keep the systems free of oxides and residual oxygen but also moderate the Ti content in the Ni binder phase during the heating stage, thus prevent the formation of intermetallic compound and ensure good wetting in the subsequent liquid phase sintering stage. © 2011 Elsevier Ltd.|
