To realize the high-efficiency and high-performance manufacture of complex high-web panels, this paper introduced electric pulse current (EPC) into the stress relaxation aging forming process of 2219 aluminum alloy and systematically studied the effects of EPC, stress, and aging time upon the microstructure and properties of 2219 aluminum alloy. It is discovered that: (a) EPC greatly enhanced t...

This paper, studied the effect of heat treatment and anodization on corrosion resistance aluminum alloy 7075 (AA7075), with a view to improving its resistance. Microstructure micro hardness anodic film samples were aid optical metallurgical microscope automated testing machine. Linear polarization methods used assess behaviour in 0.5M HCl. The microstructure annealed sample showed formation den...

The formation of low surface energy hybrid organic-inorganic micro-nanostructured zinc stearate electrodeposit transformed the anodic aluminum oxide (AAO) surface to superhydrophobic, having a water contact angle of 160 ̋. The corrosion current densities of the anodized and aluminum alloy surfaces are found to be 200 and 400 nA/cm2, respectively. In comparison, superhydrophobic anodic aluminum o...

The present study focused on the influence of different aging conditions strain-dependent damping high-strength aluminum alloy AA7075. For this purpose, artificial strategies were carried out after solution heat treatment with subsequent water quenching to identify correlations between microstructural evolution, hardness development, and individual material damping. resulting was measured using...

For purpose, various treatments are implemented evaluate impact microstructural properties on tool wear drilled holes. drilling operations have been do...

Friction Stir Welding (FSW) is a solid state process widely used to join dissimilar aluminium alloys. High quality and strength joints can be fabricated using this technique when compared to other conventional methods. The welding parameters play major role in determining the quality of the weld. This paper aims in presenting the effect of heat input on tensile properties of the joints between ...

This study aims to examine the change in microstructural and hardness values AA7075 aluminum alloy, which is frequently preferred aviation industry by applying Equal Channel Angular Pressing (ECAP) method. ECAP method, one of plastic deformation methods, has been successfully carried out 0.025mm/sec pressing speed 200°C temperature for a different route (A, Bc, C) number passes (2, 4, 8). The c...

Over the years, aluminum content in a vehicle part is increasing due to the needs to reduce weight as well as increase fuel efficiency. Most of the cast product in a vehicle part is mostly cast from A356 alloy. It is used because A356 alloy posses’excellent characteristics over other type of alloy such as cast ability, high weight-to-strength ratio, good corrosion resistance and good weld-abili...
