Interactions between the components in the Ti-Cu-Sn system at 670 K

The isothermal section of the phase diagram of the Ti-Cu-Sn system has been constructed at 670 K and phase equilibria at this temperature were determi ned. A new TiCuSn ternary compound was obtained and its crystal structure w as studied. This compound crystallizes in the LiGaGe structure type (space group P6(3)mc, a = 4.3972(1) Angstrom, c = 6.0168(2) Angstrom, which is a s uperstructure of the CaIn2 type. Reported early TiCu2Sn has a homogeneity r ange - Ti1-xCu2+xSn (x = 0.0-0.3). Electrical resistivity of TiCuSn has bee n measured, exhibiting metallic conductivity.
