Abstract

PURPOSE: To obtain a solidified body for a super hard tool material by presintering a mixture having a specified composition, mixing the resulting sialon powder with a specified amount of BN powder and Al powder, and sintering this mixture under pressure.
CONSTITUTION: Mixed powder consisting of 50mol% SiN, 25mol% AlN and 25 mol% Al2O3 is compressed, presintered at 1,400W1,500°C, and pulverized to obtain powder of a synthetic sialon presintered body. 40W6wt% This powder is mixed with 40W90wt% cubic system BN powder and 20W4wt% Al powder, mixed powder and other metal powder or alloy powder of Al and other metal. This mixture is then sintered at 1,600W1,800°C under 52,000W60,000kg/cm2 where cubic system BN is stable. Thus, many cubic system BN particles and many synthetic sialon particles are mixed and sintered, the resulting gaps are filled with Al or Al alloy three- dimensional network binder regions, and they are bonded together.
