| Research Abstract |
Titanium tri-aluminide(Al_3Ti) of tetoragonal D0_<22> type structure and(Al, Ni)_3Ti of cubic L1_2 structure has been sintered using spark plasma sintering. The tensile strength of Al_3Ti was 250MPa and that of(Al, Ni)_3Ti was 350MPa. Brake down occured at grain boundaries. Addition of 10% TiB_2 was found to improve the tensile strength of(Al, Ni)_3Ti up to 380MPa. It has also been confirmed that TiB_2-30wt%(Al, Ni)_3Ti composite has Vickers hardness as high as Hv 1700 and tensile strength of 700MPa.
