Nano-powders of 1.5TiAl and Al 2 O 3 were synthesized from 1.5TiO 2 and 3.5Al powders by high energy ball milling. Nanocrystalline Al 2 O 3 reinforced composite was consolidated by high frequency induction heated sintering within 2 min from mechanochemically synthesized powders of Al 2 O 3 and 1.5TiAl. The relative density of the composite was 99%. The average hardness and fracture toughness values obtained were 1340 kg/mm 2 and 9 MPaÁm 1=2 , respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
