Abstract
Abstract Internal-friction studies of A15 Nb3Sn, Nb3Ge, V3Ga and Laves- phase V2Zr have been carried out on foils driven in flexure. Dynamic Young's modulus (frequency) measurements have also been made. The large internal-friction feature seen below the martensitic transformation temperature (T m in Nb3Sn, which is caused by stress-induced domain-wall motion, is not found in V3Ga or Nb3Ge. This is taken as convincing proof of the non-transforming nature of V3Ga, but because of masking effects, is considered only suggestive for Nb3Ge. Laves-phase V2Zr also shows an internal-friction feature below T m, which can be also attributed to β/martensite phase-boundary motion, but its character, more peak-like than that of Nb3Sn, is quite different. Modulus hardening below T m in V2Zr follows theoretical prediction, but lack of hardening below T m in Nb3Sn is anomalous.
