Descrição: Al2O3 toughened with Ti3SiC2 was investigated for improved toughness. Hot-pressed Al2O3-Ti3SiC2 composites were manufactured and characterised. Addition of Ti3SiC2 inhibited the growth of alumina grains though a pinning mechanism. The experimental results showed that the Vickers hardness decreased with an increase in Ti3SiC2 content, and the fracture toughness and strength increased with Ti3SiC2 content. Maximum toughness (about 8.78 MPa.m1/2) and maximum strength (about 500 MPa) were achieved through the addition of 50 wt% Ti3SiC2, which is comparable to alumina toughened by other materials. 23 refs.
