Abstract

A dense nanostructured 1.5Ti-Al₂O₃ composite (volume fraction of Al₂O₃; 0.62) was simultaneously synthesized and consolidated in a high-frequency induction heated combustion synthesis method within 2 min in one step from mechanically activated powders of 1.5 TiO₂ and 2 Al. Simultaneous combustion synthesis and consolidation were accomplished under the combined effects of an induced current and mechanical pressure. Highly dense 1.5Ti-Al₂O₃ with a relative density of up to 99.8 % was produced under simultaneous application of 60 MPa of pressure and an induced current. The average hardness and fracture toughness values of the composite were 1513 kg/mm² and 7 MPa.m ^1/2, respectively.
