Titanium carbide-based cermet alloy.

摘要

There can be provided a TiC-base cermet alloy whose hardness is equal to or higher than that of a Ti(C, N)-base cermet alloy and which is excellent in toughness by strengtening the binder phase of the TiC-Base cermet alloy which does not involve the problem of denifrification at the time of sintering. The titanium-carbide-base cermet alloy comprises a hard phase which contains titanium carbide as a main component and a binder phase which contains one or both of Co and Ni as main components, wherein amounts of Ti and Mo in the binder phase satisfy the conditions, by weight T: 0.85 </= Mo (wt.%)/Ti (wt.%), and 6 wt.% </= [Ti + Mo].
