Analysis of inelasticity in high-damping Zn – Al alloys, gray irons, and iron alloys with internal friction of a magnetomechanical nature

Results are presented from a comparative analysis of the main mechanisms of internal friction in high-damping alloys based on the Zn – Al system, cast iron with flaked graphite, and iron alloys that exhibit internal friction of a magnetomechanical nature. A study is made of the damping capacity of alloys Zn – 26% Al, SCh25, and Fe – 5% Cr – 3% Al and steel 45, which are typical representatives of the types of materials in question. Their set of physico-mechanical properties is determined with allowance for damping capacity.
