Questions of the mechanism of formation of the damping condition of high-chromium ferritic steels

Abstract

The guestions of the influence of internal stresses of different origin on magnetomechanical damping in high damping ferritic alloys was widely discussed in the Internetional Conference of Guestions of Internal Friction in Solids. The participants in the discussion presented the results of their investigations of influence of the deegre of preliminary deformation static tensile stresses the number of cycles of vibrations and other characteristics on the parameters of inelastic dispersion of tnergy. The investigation of the problem is continued in this article. Primary attention is devoted to discussion of the influence of crystal line lattice deffects and stresses created by them on the damping capacity of Fe - Cr alloys.
