ABSTRACT:
The invention provides a novel class of sintered refractory and abrasive ies composed mainly of one or a combination of metal diborides such as titanium diboride TiB.sub.2, chromium diboride CrB.sub.2, tantalum diboride TaB.sub.2 and the like admixed with a minor amount of one or more kinds of metal borides exemplified by MnB, Mn.sub.3 B.sub.4, Mn.sub.2 B, Mn.sub.4 B, TiB, Ti.sub.2 B.sub.5, Ti.sub.2 B, W.sub.2 B.sub.5 and Mo.sub.2 B.sub.5. The sintered body can be prepared by conventional powder metallurgical processes such as hot pressing or sintering of a green body shaped in advance by molding in cold with the powder blend of the above described components. Further advantages are obtained by admixing the powder blend with small amounts of one or more of binder ingredients of relatively low melting points such as cobalt borides, iron borides, nickel borides and an alloy of nickel and phosphorus. So-called infusion process is also applicable for the preparation of the inventive sintered body.
