Abstract
PURPOSE: To provide wear resistance to a WC-base sintered hard alloy without lowering the impact resistance by composing part or all of the TiC component of the alloy of grains with a specified average grain size within a specified range of the total percentage and uniformly dispersing the grains in the alloy structure.
CONSTITUTION: By composing part or all of the TiC component of a WC-TiC-TaC- Co type sintered hard alloy of coarse grains with an average grain size of 7μm or more and/or grains of a double cpd. consisting of TiC≥50mol% and one or more out of the carbides and nitrides of the IVa, Va and VIa group metals in the periodic table so that the grains occupy 1W30vol% of the total percentage of the alloy and by uniformly dispersing those ultra coarse grains in the alloy structure, the wear resistance of the alloy is considerably enhanced without lowering the superior impact resistance of an ordinary WC-base sintered hard alloy.
