Abstract
The cubic‐tetragonal phase transformation in V3Si and Nb3Sn has been investigated dynamically with optical and x‐ray techniques. For Nb3Sn a simple shear on the {110} 〈11̄0〉 completely describes the lamellar morphology in the tetragonal state. The lamellar structure and associated shear are concluded to arise from an accommodation of internal stresses and are a result of, not a mechanism for, the transformation. All our observations are consistent with a continuous transformation from the cubic to tetragonal state with no evidence of hysteresis or the coexistence of the two phases.Keywords
