Abstract

To study mechanical and physical properties of solid bodies, it is important to know the behavior of rms velocities of atomic vibrations, especially accompanying changes in the ambient temperature. Therefore, we investigate binary iron alloys in the vicinities of phase transition temperatures using Mossbauer spectroscopy. The rms velocities of atomic vibrations demonstrate that 3d-3p direct chemical bonds for Si and 3d-4p direct chemical bonds for Ge are broken (formed) at the phase transition temperature; as a consequence, the velocities of atomic vibrations sharply increase.
