Cemented carbide containing muli-component high entropy carbide and/or multi-component high entropy alloy

Abstract

A sintered cemented carbide includes a high entropy carbide or a spinodal decomposed product thereof; and a metallic binder containing at least one of Co, Co—Ru, Ni, Co—Ni, Co—Cr, Co—Ni—Cr, Co—Re, Co—Ni—Re, Co—Ni—Ru, or a high entropy alloy, wherein the high entropy carbide is a single-phase solid solution carbide comprising four to ten metallic elements, and the spinodal decomposed product thereof includes two chemically distinct phases having a same crystal structure. A sintered cemented carbide also includes a carbide including at least one of WC, TiC, ZrC, HfC, NbC, TaC, or Cr3C2; and a metallic binder including a high entropy alloy. The high entropy alloy is an alloy of four to ten alloy elements selected from Al, Be, Fe, Co, Cr, Ni, Cu, W, V, Zr, Ti, Mn, Hf, Nb, Mo, Ru, Re, Ge, Sn, C, B, or Si.
