In this study, the mechanical properties and strengthening mechanisms resulting from evolution of microstructure in an Al-4.39Mg-2.78Zn-0.42Cu (wt%) alloy were investigated through various heat treatment processes. Compared with conventional T6 process, both final thermomechanical (FTMT) T6+deformation (T6D) process found to significantly increase strength alloy. FTMT T6D treated alloys, distribution nano-sized T-Mg32(Al, Zn, Cu)49 phase dislocations observed throughout microstructure....
Al–Cu–Mg–Fe–Ni alloys are widely used in high temperature structural materials such as automobile engine cylinders and pistons, owning to their good mechanical properties. In this work, the effect of Fe Ni content, solution treated, aged process on microstructure properties were investigated by optical microscopy (OM), scanning electron (SEM), hardness tensile tests. Transmission microscope (TEM) high–resolution TEM determine existence S phase Al9FeNi precipitates. The treatment followed is...
Nanostructuring of metals is nowadays considered as a promising strategy towards the development materials with enhanced electrochemical performance. Porous and fully dense CuNi films were electrodeposited on Cu plate by electrodeposition in view their application electrocatalytic for hydrogen evolution reaction (HER). film synthesized using bubble template method an acidic electrolyte, while from citrate-sulphate bath addition saccharine grain refiner. The prepared characterized chemically...
Ni-based bimetallic films with 20 at.% and 45 Cu mesostructured surfaces were prepared by electrodeposition from an aqueous solution containing micelles of P123 triblock copolymer serving as a structure-directing agent. The pH value the electrolytic had key effect on both resulting Cu/Ni ratio surface topology. catalytic activity CuNi toward hydrogen evolution reaction was investigated cyclic voltammetry (CV) in 1 M KOH electrolyte at room temperature. Cu45Ni55 film showed highest (even...
Although nanoporous materials have been fabricated by electrodeposition using micelles of P-123 as structure-directing entities, the possible geometry obtained has limited to films. Herein, a novel dual-template assisted method fabricate Cu/Cu2O porous nanowires (PNs) polymeric soft template and polycarbonate membranes hard is reported. These consist skeleton with nanosized pores 20 nm on average crystallized ligaments. Morphology, composition, crystal structure are systematically...
Magnetic chitosan hydrogel has aroused immense attention in recent years due to their biomedical significance and magnetic responsiveness. Here, A new electrodeposition method is reported for the fabrication of a novel CuNi-based freestanding film (MCFF) an acidic plating bath containing SDS-modified CuNi NPs. Contrary chitosan's anodic cathodic deposition, which typically involves electrochemical oxidation, synthetic process triggered by coordination with Cu Ni ions situ generated...
