Title:
SINTERED BODY AND CUTTING TOOL CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2017/203738
Kind Code:
A1
Abstract:
This sintered body comprises a first material and a second material, wherein the first material is partially-stabilized ZrO2 in which 5-90 vol% of Al2O3 with respect to all the first material is dispersed at crystal grain boundaries or in crystal grains, the second material contains at least one of sialon, silicon nitride, and titanium nitride, and the sintered body contains 1-50 vol% of the first material.
