Acoustic and damping properties of known and test chromium steels are investigated after heat treatment. Test metal microstructure and physicomechanical properties are studied. The increase in sound energy attenuation for a martensitic structure is determined. As a result of steel quenching, attenuation is reduced due to dislocation annihilation.
Sound radiation of well-known and melted alloys, and test specimen microstructure are studied, and the effect of nonmetallic inclusions on damping effect is evaluated.
