Influence of Transition Metals Ti and Co on Interfacial Microstructure and Strength of Copper–graphene Composites
Iron Steel Vanadium Titanium,2020,Vol 41,No. 05
Transition metals Ti and Co were separately introduced into copper–graphene composites by matrix alloying and powder metallurgy methods. The effects of Ti and Co on the strength of copper–graphene composites were compared by tensile tests. The microstructure and interface structure of copper–graphene composites were characterized by a scanning electron microscope (SEM), a transmission electron microscope (TEM), and a Raman spectrometer. With the addition of Ti, a large number of TiC nanoparticles were formed on the interface, which promoted the interface bonding without increasing graphene defects, and the tensile strength increased from 223 MPa to 256 MPa. Nevertheless, amorphous carbon appeared at the interface of Co-doped composites. It increased graphene defects and was not conducive to play the role of strengthening phase and transferring interface load, resulting in the strength decreased from 223 MPa to 192 MPa.
