Abstract Relationship between carbon content and height of the internal friction peak of carbon diffusionin pure nickel have been measured. In addition to this, the relationship between height of theinternal friction peak and the carbon content in the manganese steel containing 18.5% manganesewas also accurately determined, the obtained curve shows that the intersection of axis indicating thesolubility of carbon for this steel really exist. So that, the internal friction peak induced by the interstitial atoms diffusion in the pure metalof face center cubic crystal was owing to the rotation of the atomic pair of two neighbouring atomsin the crystal lattice under the action of stress. The state of carbon atoms may be modified by ad-dition of alloying elements, it can considerably reduce the possibility of formation of carbon atompair, consequently the internal friction peak in the high manganese alloy steel is primarily due tothe rotation of carbon-manganese atom pair.
