Abstract
The internal friction peak in tantalum arising from the diffusion of interstitial carbon has been located at 338°C for vibration frequencies of 0.55 cps. The corresponding activation energy is 39.6 kcal. The identification of this peak is made difficult by its proximity to the nitrogen peak. However, the two can be distinguished by the lesser stability of the carbon peak with respect to aging at 400°C and by a different dependence of peak height on solute concentration.Keywords
