Description

V-Ti-Cr-Si type alloys containing Al and Y were prepared for structural materials application of fusion reactors. The condition of heat treatment, tensile properties and deformation microstructures were examined for two type alloys referred as V-25Ti-15Cr and V-5Ti-5Cr. The neutron irradiation behavior was also studied. Tensile test were conducted using miniature-type specimens at temperatures from 300 to 1273K. The alloy V-25Ti-15Cr showed the strength twice as high as V-5Ti-5Cr at temperatures from 300 to 873 K. Ductility of V-5Ti-5Cr alloy was larger than that of V-25Ti-15Cr at lower temperatures. The amount of void swelling after neutron irradiation of the two alloys was very low level compared with that of various vanadium alloys. (author)
