VGa-based alloys as candidate materials for fusion reactor application
1996
Abstract Results of the experimental study of some physical, mechanical and technological properties of the reduced activation vanadium—gallium-based alloys are presented. The activation calculations show that Ga has the lowest cooling time not only in comparison with alloying elements Ti and Cr in low activation VTiCr alloys but also with vanadium. The effect of Ga(1–8 at%), Cr (5–6 at%) and Ce(0.05–0.1 at%) on workability, mechanical properties, thermal conductivity, elastic modulus (E,G), and Poisson's ratio of VGa was studied. The same properties of some are also studied. The level of tensile properties, thermal conductivity and elastic properties of VGa alloys are comparable with VTiCr alloys, but their activation parameters and ductility are superior. The experimental results make it possible to recommend VGa-based alloys as reduced activation structure materials for fusion reactors.
