Abstract

X-ray diffraction measurements were carried out on powdered single crystals of nearly stoichiometric Fe3Si. The experimental data obtained in the temperature range from room temperature up to 750‡ C in terms of long-range order, thermal expansion, phase transition and Debye temperature (together with values of the Curie temperature) support the existence of two modifications of the DO3 structure for Fe-26 at% Si alloys and a phase transition in the DO3 structure field at 595‡ C. The high-temperature modification has a smaller thermal expansion coefficient, a higher Curie temperature and a higher Debye temperature.
