Title: Wear-resistant boride composites with high percentage of reinforcement phase

Abstract

A highly wear resistant sintered, hot pressed, or otherwise compacted ceramic composite material is described, consisting of two discrete phases of the form Al.sub.xMg.sub.yB.sub.14 where x and y .ltoreq.1 or like hard, orthorhombic compounds, and TiB.sub.2 or like Group IVB transition metal di-borides, and with an unexpectedly high content of transition metal di-boride in the range from 40 to 90 percent (28 to 85 volume percent).
