Well-characterized transforming (T) and nontransforming (NT) V/sub 3/Si single-crystal samples have been investigated under hydrostatic pressures up to 29 kbar. Above the critical pressure P/sub c/, the superconducting transition temperature T/sub c/ of the T sample was found to increase continuously with pressure, with only a reduction in partialT/sub c//partialP. The value of partialT/sub c//partialP for the T sample above P/sub c/ is similar as to that for the NT sample. A pressure-induced phase transition in the NT sample at 28.6 kbar was observed. The results are discussed and compared with some of the predictions of various models on A15 high-T/sub c/ superconductors.
