Method of producing titanium alloy composite material

Abstract

A method of producing a titanium alloy composite material comprises mixing carbon fibers and a powder of an element which forms a carbide in reaction with carbon, subliming the element under high temperature vacuum, and coating the carbon fibers with a layer containing the element and the carbide to produce coated carbon fibers. The method further comprises mixing the coated carbon fibers and titanium alloy powder to form a mixture, and applying a mechanical impact force to the mixture to fix the carbon fibers on the surface of the titanium alloy powder to obtain a carbon fiber-fixed titanium alloy powder. The method further comprises sintering the carbon fiber-fixed titanium alloy powder to form a sintered body and plastic working the sintered body to disperse the carbon fibers in crystal grains of the titanium alloy.
