Plastic stress‐strain characteristics of V3Si single crystals, oriented for [110] compression, have been ascertained under dynamic conditions between 1200 and 1800 °C. This is believed to be the first such report on the A‐15 compound superconductors. In the range 1200–1500 °C, yield strength is very temperature sensitive, whereas the sensitivty is not very pronounced between 1600 and 1800 °C. In addition, substructures introduced by a ∼7% compressive strain at different temperatures appear to have no deleterious effects on transition temperatures and transition widths.
