Abstract

A multicomponent carbide has at least five transition metals, and a valence electron concentration (VEC) is greater 8.80 electrons. Preferred off-equiatomic multicomponent carbides have five transition metals and a VEC of more than 8.80. Preferred equiatomic multicomponent carbides have five transition metals and a VEC of 9.00 or greater. The valence electron configuration is important for its relationship to the mechanical properties of carbides. Since carbon forms four bonds, when there are more than four valence electrons available from the metals, there are excess electrons in the system. This increases metallic character of bonding and therefore allows for more ductility and higher toughness.
