摘要：

The crystal structure of the R-phase in Ti-Ni alloy is determined by the X-ray powder diffraction method. The Pawley :method (whole powder pattern decomposition method) and the Rietveld method were used for the analysis. The results of the analysis indicate the space group of the R-phase is P3 rather than <P(3)over bar 1m>. The atomic positions obtained are compared with those of Au-Cd. The transformation mechanism is also discussed in comparison with that for Au-Cd alloy.
