· VIr3

VIr3 is an intermetallic compound in the vanadium-iridium system, combining a refractory transition metal (vanadium) with the noble metal iridium to create a dense metallic phase with high stiffness. This material family is primarily of research and developmental interest, studied for applications requiring extreme hardness, chemical resistance, and thermal stability in combination with metallic properties.
