Abstract
The drawing process severely deforms commercial AA1070 alloy for electrical wire, reducing a rod from a diameter of 2.0 mm to 0.4 mm, followed by annealing. The annealing process was conducted at various temperatures ranging from 200℃ to 450℃, with each temperature maintained for 1hour. The effects of increasing annealing.....

Abstract
Modulation doping occurs in a heterojunction where a charge carrier-rich material transfers charge to a carrier-deficient material. The modulation-doped material is intentionally selected to have higher charge carrier mobility than the modulation dopant material, so that the overall electrical conductivity can be boosted. Although this modulation doping strategy has proven.....

https://doi.org/10.3365/KJMM.2021.59.11.821
Abstract
A three-dimensionally interconnected graphene-reinforced Cu (3Di Gr-Cu) composite was synthesized using a simple two-step process technique which involves the mechanical compaction of micronsized Cu particles followed by chemical vapor deposition (CVD) at 995 ℃. The microstructural properties of pure Cu and the 3Di Gr-Cu composite were investigated by optical.....

Abstract
Cu-Ti alloys were strengthened by Cu4Ti intermetallic compound precipitation in a Cu matrix during aging. The Cu-3.5 wt% Ti(Cu-4.6 at% Ti) alloys without deformation and with uniform and non-uniform deformation were aged at 450 oC for various times after solution treatment at 885 oC. The uniformly and non-uniformly deformed alloys.....
