Resumo
We have studied the influence of thermal treatment on the dynamic Young’s modulus, linear and nonlinear internal friction, and Young’s modulus defect of Ni55Fe18Ga27 alloy single crystals. Strong variations of all these parameters were observed and explained by changes in the concentration of vacancies in the crystal lattice. It is concluded that vacancies form atmospheres near twin boundaries, the density of which (but not their extension) strongly depend on the concentration of vacancies.
