“…The rapid development of aerospace, machinery industry and electronics industry in recent years the requirement of materials with higher physical properties, especially the high electrical conductivity, for improving the energy efficiency [1][2][3]. Lots of research work have been made to study and improve Cu and its alloy which is the metal with second highest electrical conductivity in conventional operating environment [4][5][6][7][8] . Further improvement of the electrical conductivity can be achieved by improving the purity or getting single crystallization, which is quite limited for practical use due to its high cost and low yield.…”

Copper (Cu) and its related composites are widely used and hence extremely important in industrial applications. Much efforts haves been made to improve the physical properties of Cu, but usually lead to degradation of electrical performance. Herein, this work develops a facile way to fabricate layer-structured graphene/copper composite using graphene powder sprayed on Cu foil as building blocks. Compared to pure Cu bulk, significant improvement of both the electrical conductivity of 105.12% IACS and also ~17% enhanced tensile strength is achieved. This strategy provides a versatile way to produce high-performance Cu composite in large quantity with low cost for practical applications.

“…Process parameters play a pivotal role in compressive strength and microhardness [16]. Sintering at 750 • C with 0.1 wt.% graphene yields the best electrical and mechanical characteristics [17]. Varying mixing technique, sintering temperature, and oxygen content modifies Ti-O alloys' shape, dispersion, and solid solution microstructure [18].…”

This study focused on developing microstructural, thermal, and radiation shielding changes in Al50Si25B25 powders using mechanical alloying techniques. Based on the x‐ray powder diffraction data, the crystallite size and microstrain of the 100‐hours milled powder were calculated as 0.25 nm and 50.33 %, respectively. The solubility of silicon in the α‐aluminium matrix increased with longer mechanical alloying duration. Transmission electron microscope analyses further showed that the alloy particulates had an average size of 3 μm and an average grain size of 0.226 nm. The radiation shielding properties of the Al50Si25B25 powders indicated that the Linear Attenuation Coefficient value increased from 0.0554±0.1689 cm−1 to 1.0632±0.2425 cm−1 with an increase in the thickness of the Al50Si25B25 alloy. This work successfully demonstrated the potential of mechanical alloying techniques to enhance the microstructural and thermal properties of Al50Si25B25 powders. It highlighted their effectiveness in providing radiation shielding capabilities when varying the thickness of the alloy.
