Abstract

We report the discovery of a new, apparently stable, large unit cell bcc structure in slowly cooled TiCrSi alloys. This bcc phase, which is also found in TiMnSi and TiVSi alloys, is likely the crystal approximant related to i-phase formation in the Ti-3d transition metal alloys. Single phase samples of this material were obtained by prolonged annealing at 1200°C. We report the results of a Rietveld structural analysis performed on X-ray powder data obtained from these single phase samples which indicate that this phase is closely related to the α(AlMnSi) phase, a crystal approximant related to the icosahedral phase in AlMnSi systems.
