Composites of TiB 2 -tetragonal Al 3 Ti and TiB 2 -cubic (Al,Ni) 3 Ti have been fabricated using spark plasma sintering method at the temperature between 1173 and 1573 K. When TiB 2 (Al,Ni) 3 Ti specimens were sintered between 1273 and 1373 K, (Al,Ni) 3 Ti filled in space between TiB 2 grains and dense samples were obtained. On the other hand, when TiB 2 (Al,Ni) 3 Ti specimens were sintered at above 1473 K, (Al,Ni) 3 Ti evaporated and monolithic TiB 2 were obtained. A similar results have been obtained for the TiB 2 Al 3 Ti composites. The highest bending strength of TiB 2 (Al,Ni) 3 Ti specimens were 660 MPa obtained for TiB 2 30 mass%(Al,Ni) 3 Ti sintered at 1373 K. The highest bending strength of TiB 2 Al 3 Ti composites were 610 MPa obtained for TiB 2 30 mass%Al 3 Ti sintered at 1473 K. The Vickers hardness of TiB 2 (Al,Ni) 3 Ti composites increased as the sintering temperature increased and the maximum value of 2100 Hv were obtained by the sintering at 1573 K.
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.
