Dense TiAl3/Ti3AlC2/Al2O3 composites were synthesised from Al, TiO2 and TiC powder mixtures at 1250 C and 50 MPa for 10 min using an in-situ reaction/hot-pressing method. The reaction kinetics, microstructure, mechanical properties and toughening mechanism of the fabricated composites were investiga...
