Abstract
An ultra-hard composite material and a method for manufacturing the same, including mixing a metal carbide powder and a multi-element high-entropy alloy powder to form a mixture, green compacting the mixture, and sintering the mixture to form the ultra-hard composite material. The described multi-element high-entropy alloy consists of five to eleven principal elements, with every principal element occupying a 5 to 35 molar percentage of the alloy.
Claims12
A method for manufacturing an ultra-hard composite material, comprising:
- mixing a ceramic phase powder consisting of only one metal carbide and a multi-element high-entropy alloy powder to form a mixture;
- green compacting the mixture;
- and
- sintering the mixture to form an ultra-hard composite material,
- wherein the multi-element high-entropy alloy powder consists of 5 to 11 elements, with every principal element occupying a 5 to 35 molar percentage of the multi-element high-entropy alloy powder.
