THE ACCURATE MOLECULAR FORMULA OF "Ti_(11)Ni_(14)" PHASE
THE ACCURATE MOLECULAR FORMULA OF "Ti_(11)Ni_(14)"　PHASE

From the orientation relationship between "Ti11Ni14" phase and matrix phase (B2),the accurate molecular formula of "Ti11N14" phase has been derived in this paper. The results also show that the rhombohedral unit cell of the "Ti11Ni14" phase includes six Ti atoms, seven Ni atoms and one vacancy, belonging to space group R3.
