Bonding Characteristics of Al and Al-Alloy Strips: Processed by Severe Plastic Deformation
نویسندگان
چکیده
In this paper, the study of efficient bonding characteristics of AA6014 and AA1050 metal strips is carried out for Accumulative Roll Bonding (ARB) process. Among various Severe Plastic Deformation (SPD) techniques, ARB process is widely used due to its ability to produce ultra-fine grained ( UFG) or nanostructured bulk material. It has been observed that, if the experimental pressure and corresponding temperature achieve their respective threshold values, then the bonding can be successfully joined as compared to the solid state welding.

Effect of Pre-existing Nano Sized Precipitates on Microstructure and Mechanical Property of Al-0.2wt% Sc Highly Deformed by ARB Process
The effect of pre-existing nano sized precipitates on the mechanisms and rate of grain refinement has been investigated during the severe plastic deformation. A binary Al–0.2Sc alloy, containing coherent Al3Sc particles, of 3.62 nm in diameter has been deformed by accumulative roll bonding up to 10 cycles. The resulting deformed structures were quantitatively analyzed using electron backscatter...
متن کاملA new approach for fabrication of bulk MMCs using Accumulative Channel-die Compression Bonding (ACCB)
A new severe plastic deformation (SPD) based technique entitled Accumulative channel-die compression bonding (ACCB) is proposed for the fabrication of high strength multi-layered Al/Cu composites for the first time. In order to primarily demonstrate the capabilities of ACCB in the fabrication of metal matrix composites (MMCs), AA 1050 and pure Cu strips were processed. The primary Al/Cu sandwic...
متن کاملCorrosion Behavior of Al-2wt%Cu Alloy Processed By Accumulative Roll Bonding (ARB) Process
Accumulative roll bonding (ARB) imposes severe plastic strain on materials without changing the specimen dimensions. ARB process is mostly appropriate for practical applications because it can be performed readily by the conventional rolling process. An Al-2wt%Cu alloy was subjected to ARB process up to a strain of 4.8. Stacking of materials and conventional roll-bonding are repeated in the pro...
