Influence of Interstitial Solutes on Elasticity and Damping of Chromium near Its Néel Temperature

Abstract
Carbon and nitrogen influence the Young's modulus and the damping behavior of chromium near its Néel temperature; the thermal history is also important. Changes in the modulus and the damping induced by varying the thermal history are attributed to changes in the characteristics of the interstitial dispersions, rather than to variations in the concentration of soluble interstitials. The stress sensitivity of the modulus and damping anomalies in unalloyed chromium suggest that stresses associated with the nitride and carbide dispersions contribute to the changes observed in the alloys.
