Carbon fibers coated with graphene reinforced TiAl alloy composite with high strength and toughness

Abstract To meet the more rigorous requirement in aerospace industry, recent studies on strengthening and toughening TiAl alloys mostly focus on high Nb addition, which inevitably bring in an increasing of density. In this study, a carbon fibers coated with graphene reinforced TiAl alloy composite w...
