INTERSTITIAL SOLUTE ANELASTICITY AND MECHANICAL BEHAVIOR OF GROUP Vb METALS

Abstract
An argument is presented that the difference in Snoek-related anelastic behavior of the Group Vb metals Nb and Ta observed by Weller and Co-workers vis-a-vis Powers and Doyle, Gibala and Wert and other investigators is related to metal purity. Weller's results are unique in their use of very high purity base metals. These materials apparently do not exhibit the discrete anelastic relaxations of interstitial solute singles, pairs, triplets and other small atom clusters observed by other investigators in materials of lesser purity. This analysis of anelastic data is consistent with mechanisms of solute association effects which have been used to account for solid solution softening observed in mechanical behavior data on Nb- and Ta-base ternary alloys.
