摘要

Use VDBF-250 vacuum hot pressing sintering furnace TiC10/Cu-Al_2O_3 composite was prepared by vacuum-pressed sintering. In the cold isotatic pressing machine for sintering state sample was cold isostatic pressing and detection performance. Using the Gleeble-1500D simulator, the high-temperature plastic deformation behavior of TiC10/Cu-Al_2O_3 composite was investigated at 450～850°C with the strain rate of 0.001～1s~(-1) and total strain of 0.7 the dynamic recrystallization behavior of the composite was studied. The results show that the density, microhardness and electrical conductivity of the composite are 98.53%, 161HV and 48.7%IACS. After the isostatic cool pressing, The comprehensive performance of the material were improved. The softening mechanism of the dynamic recrystallization is a feature of high-temperature flow stress-strain curves of the composites, and the peak stress increases with the decrease of deformation temperature or the increase of strain rate, and Belong to temperature and strain rate sensitive material.
