Abstract

This paper aims to investigate effect of spark plasma sintering temperature on mechanical property of Ti + ZrO2. The samples were prepared by SPS system with the different sintering temperature containing 900, 1,000, and 1,100 ºC under the pressing pressure of 30 MPa in vacuum. The results show that hardness of Ti + 2 wt.% ZrO2 alloy increases with increasing sintering temperature. The highest hardness was 363 HV while suitable temperature for sintering Ti + 2 wt.% ZrO2 alloy was 1,100 ºC. Further, the microstructure and crystal structure of all samples were single-α-phase structure with different in elements dispersion, which was related to amount of lattice expansion in the HCP structure. © 2021 Trans Tech Publications Ltd, Switzerland.
