Influence of annealing on indicatory surface of anelastic-elastic body of GeSi

The temperature-dependent behavior of internal friction Q− 1 and elastic modulus Е of Ge0.95Si0.05 was investigated and represented through the plotting of 3D “indicatory surface of anelastic-elastic body”. On 3D temperature dependence of the elastic modulus E and internal friction Q− 1 (“indicatory surface of anelastic-elastic body”) of Ge0.95Si0.05 found out the dominant internal friction maximum Q− 1M3 at temperature ТМ3 ≈ 510 К. In the area of existence of the internal friction maximum was the relaxation of the elastic modulus ΔE/E. The absolute values of the elastic modulus increased after annealing, confirming the hardening of Ge0.95Si0.05 crystal. Internal friction maximum Q− 1М1 at temperature TМ1 ≈ 387 K and internal friction maximum Q− 1М2 at temperature TМ2 ≈ 421 K were discovered due to the process of changing the vacancies V number in the vacancy complexes V-V-V under the influence of variable ultrasound deformation εUS. .
