Carbon–Titanium Composite Material with Copper Coated Fiber: The Structure and Mechanical Properties
The paper sets forth the basics of laboratory technology for producing a composite material with the matrix based on the VT16 alloy (Ti–Al–Mo–V) and with composite reinforcing layers using UMT49-12K-EP carbon fibers. The reinforcing layers are formed by impregnating the carbon fiber with a relatively fusible Ti–Cu eutectic formed at the interface of titanium and copper that coats the carbon fiber. The structure and mechanical properties of the composite such as strength, modulus of elasticity in bending, and fracture toughness have been investigated. The mean bending strength value is 1729 MPa (maximum 1916 MPa), Young’s modulus is 136.3 GPa (maximum 167.1 GPa), and the critical stress intensity factor is 40.1 MPa m1/2 (maximum 45.1 MPa m1/2). Improvements in the processes of copper coating on carbon fibers and fiber layup will allow to avoid scattering of mechanical properties of carbon-titanium composite.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
