alloys[18-20]. The Ti2Ni intermetallic compound has good combination of ductility because of its face-center-cubic crystal structure[14]. ISHIDA et al[21] indicated that TiNi alloy containing spherical... by the laser melting deposition. Abrasive wear resistance of the Ti2Ni/TiNi alloy was evaluated, and the corresponding mechanism was discussed. 2 Experimental Commercial pure Ti-Ni elemental powder blends......
