Microstructure-property relations of eutectic V-Si and V-B alloys

Abstract

Subject of the present work are principle studies on V-Si and V-B alloys with hypo-and hypereutectic compositions, regarding the effects of primary phase solidification and the formation of binary microstructures on the resulting mechanical properties. For this purpose, button shaped samples were produced by arc-melting, metallographically prepared and analyzed by scanning electron microscopy. Furthermore, room temperature compression tests have been carried out and the resulting deformations were subsequently analyzed by using electron backscatter diffraction. As a conclusion, the materials' failure behavior was characterized and discussed with respect to the developed microstructure. The main goal of the experiments conducted is to critically discuss previously published works on the V-Si and V-B alloying systems and to obtain more profound insights on microstructure-property relations with respect to the strengthening effects and plastic deformability.
