Abstract
A Mo/Ti3SiC2 laminated composite is prepared by spark plasma sintering at 1300°C under a pressure of 50MPa. Al powder is used as sintering aid to assist the formation of Ti3SiC2. The fabricated composites were annealed at 800, 1000 and 1150°C under vacuum for 5, 10, 20 and 40h to study the composite's interfacial phase stability at high temperature. Three interfacial layers, namely Mo2C layer, AlMoSi layer and Ti5Si3 solid solution layer are formed during sintering. Experimental results show that the Mo/Ti3SiC2 layered composite prepared in this study has good interfacial phase stability up to at least 1000°C and the growth of the interfacial layer does not show strong dependence on annealing time. However, after being exposed to 1150°C for 10h, cracks formed at the interface.
