초록
Nanopowders of TiO and Al were fabricated using high energy ball milling. Dense nanostuctured 3Ti-Al2O3 composite wassimultaneously synthesized and consolidated by high frequency induction heated combustion synthesis method within 2 minin one step from mechanically activated powders of 3 TiO and 2 Al. Highly dense 3Ti-Al2O3 with relative density of up to99.5% was produced under simultaneous application of a 80 MPa pressure and the induced current. The average hardnessand fracture toughness values of the composite were 1445 kg/mm2and 7.2 MPa • m1/2, respectively.
