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...

because of high strength to weight ratio, 6061 aluminum has many applications in different industries like automotive and aerospace industries and can help to reduction of fuel consumption. forming limit diagram (fld) is a useful method for sheet metal formability identification. whereas calculation of forming limit diagram by experimental tests is expensive and time consumption, in the present...

Ultrasonic additive manufacturing (UAM) is a rapid prototyping technology that features a metal joining process through ultrasonic welding. The bonding mechanisms and mechanics of UAM have been investigated for decades. Meanwhile, the plastic deformations of metals were extensively studied by many researchers for their significant roles in bond formation. However, most of these research efforts...

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 ...

The experimental investigation of hybrid metal matrix composites with fly ash and graphite reinforced aluminium alloy (Al 6061) composites samples, processed by stir casting route are reported. The aluminium alloy was reinforced with 3 wt.%, 6 wt.%, 9 wt.% fly ash and fixed 3 wt.% of graphite to mixture the hybrid composite. Hardness of the hybrid composite were tested it was found that when th...

The conjoint influence of welding and artificial aging on mechanical properties were investigated for extrusions of aluminum alloy 6063, 6061, and 6005A. Uniaxial tensile tests were conducted on the aluminum alloys 6063-T4, 6061-T4, and 6005A-T1 in both the as-received (AR) and as-welded (AW) conditions. Tensile tests were also conducted on the AR and AW alloys, subsequent to artificial aging. ...

The electrochemical and corrosion behaviour of Al-6061, Al-4.5%Cu and Al-7.5%Cu alloys were studied in 0.50 M KSCN solution at 25 C. Open-circuit potential, Tafel polarization and ICP-AES measurements were used to study the uniform corrosion process on the surfaces of the tested alloys. Cyclic polarization measurements were employed for pitting corrosion studies. Obtained results were compared ...
