There has been a considerable interest to develop the silicide alloys as high temperature structural materials because of their excellent high temperature stability and strength, however, their lack of room temperature ductility and toughness was a main obstacle for the application. In order to improve ductility while maintaining good high temperature properties, possible refractory metal-silicide eutectic alloys composed of fine two phases were prepared by VAR(Vacuum Arc Remelting). Three silicide alloys, Nb-Nb_3Si, Ti-Ti_5Si_3, V-V_3Si, were selected as prospecting silicide eutectics and those high temperature characteristics were evaluated by high temperature compression test.
