Abstract
Progress of the crystallographic transformation as well as the twinned tetragonal structure in indium-rich thallium alloy single crystals was studied by means of X-ray diffraction topography. Single crystals examined are prepared by both the recrystallization and Bridgman methods. The transformation from the fcc phase and the fct phase on cooling is martensitic, and single crystals transform by the migration of a single interface. Since no evidence for diffusion was obtained, the observed phases are necessarily metastable and, therefore, usual representation of the two phase field in an equilibrium phase seems to be inappropriate.
