The variation of the pinning force with microstructure and with the Ginzburg-Landau parameter is studied for 53 vanadium and vanadium alloy specimens. Vanadium-carbide precipitates are used as pinning centers. The Ginzburg-Landau parameter is varied by alloying the vanadium with small quantities of gallium or niobium. Alloy compositions of V-0.20ao Ga, V-1.05ao Ga, V-2.96a0 Ga, and V-4.01ao Nb are used.
