It is well known that some of the high-transition-temperature superconductors with β-W structure exhibit lattice instability and transform martensitically from the cubic to the tetragonal structure.1,2 In our recent low-temperature heat capacity measurements of V3Si,3 distinct superconducting transitions corresponding to both the cubic and tetragonal phases were observed whenever the transformation occurred. Reported in this communication are similar observations on Nb3Sn and related compounds.
