| Abstract | ||
| Recent advance in high-speed cutting materials have focused on reinforcing alumina with different carbides and nitrides in order to improve hardness and fracture toughness, this composites materials use in cutting tools application. The present study concert on properties of cutting tools made by Al2O3 reinforcement by Mg-PsZ. The added weight fractions from ZrO2 are (15% , 20%). The materials cold-pressed at (5, 7, 10) ton, at (1400, 1500, 1600 Co) in two hours. The result shows increasing in hardness and densities values of specimen with the increasing the mixing percent also, there is a signification enhancement of specimen properties with increased temperature and pressure, the approperte temperature is 1600 Co with pressure 10 ton. | ||
