Abstract

PURPOSE: To provide a lightweight sintered hard alloy of very high hardness by sintering TiB2 partcles with an Ni-B alloy of a specified composition as a binder.
CONSTITUTION: About 10% Ni-B alloy powder contg. 4W14.2% B as a biner is added to ultra hard TiB2 particles of 0.8μ in average particle size and well mixed while agitating. This mixture is compacted under a pressure of 3W4tons/cm2, put in a heating furnace, and sintered by heating at 1450°C for 1hr in a purified hydrogen atmosphere. Wettability between TiB2 and the Ni-B alloy of te above-mentioned composition is excellent, and they do not react at such a high temp., so a strong sintered body is obtd. Since TiB2 is higher than WC and TiC in hardness and lower than they in specific gravity, a lightweight sintered hard alloy with superior resistance is obtd.
