In the present study, various literature based on high strain rate behaviour of ultrafine-grained (UFG) aluminium alloys produced through severe plastic deformation techniques have been discussed. It was observed from that under (3000–120000 s−1) adiabatic shear bands (ASBs) were formed which is main reason for dynamic failure. These ASBs failure Al when they exposed to impact. The are mainly t...

In this work, the effect of ageing and retrogression on polarization resistance Al 6061 was assessed, in order to improve corrosion alloy with a negligible tensile strength. The behavior studied by exposing an simulated marine environment, then, current density (icorr) measured. obtained results were correlated strength (TS) reported elsewhere both measured, icorr TS modeled multiple linear reg...

Joining of the similar & dissimilar materials alloys using heat friction in currently being used, especially for non-ferrous which are considered as non-weldable alloys. Al 2024-T6 6061-T6 having length 70mm and 12mm diameter were welded by welding process. Similar samples obtained applying different combinations parameters like pressure 30bar, forging from 50 to 60 bar, rotational speed 22...

AA 6061 has gathered wide acceptance in the fabrication of the light structures required to high strength. Compared to the fusion welding processes that are used for joining structural aluminium alloys, friction stir welding (FSW) process is an emerging solid state joining process in which the material that is being welded does not melt and recast. In this experimental work, an extensive invest...

High-speed machining is considered to be a promising technique due its advantages, such as high productivity and better product quality. With paradigm shift towards sustainable practices, the energy consumption analysis of high-speed also gaining ever-increasing importance. The current article addresses this issue presents detailed specific cutting (SCE) surface finish (Ra) during conventional ...

Cracking is a major concern in welding aluminum alloys. Although weld solidification cracks can be eliminated through addition of filler alloy, the additives modify the alloy or base-metal constituents and may not always be desirable. High-energy beam processes, such as electron-beam welding, that result in minimal heat input reduce crack sensitivity, but their high cost limits their applicatio...

During the solution heat treatment (SHT) process of aluminum alloys, precipitates dissolve into matrix. To predict dissolution time, modeling isothermal in 6061 alloy during SHT was conducted. A precipitate model established, and flowchart designed as well. Then explicit finite-difference method employed to solve model, mobile nodes used deal with moving interface. The simulation based on real ...

A three-dimensional numerical model is used to simulate the Friction Stir Welding (FSW) process using the computational fluid dynamics package ‘FLUENT’. Two mechanical models: the Couette and the Visco-Plastic fluid flow models for Al-6061-T6 were simulated. The simulation results are compared to experimental data for Al 6061-T6 welded at high rotational (1500–5000 rpm) and travel speeds rangin...

Abstract In this work, a systematic study on the interactions between aluminum oxide films and TiB 2 grain refiner particles their effect refinement behavior have been conducted. Oxide were introduced into commercial purity melt by adding AA 6061 alloy chips while Al-3T-1B master alloy. Strong sedimentation of was observed in without chip addition during long-time settling. Most settled accumul...
