Change In Microstructure and Mechanical Properties Of Four-Layer Stack ARB Processed Complex Aluminum Sheet with Annealing

Autor: Sang-Hyeon Jo, Seong-Hee Lee

Publikováno v: Archives of Metallurgy and Materials, Vol vol. 66, Iss No 3, Pp 759-763 (2021)

The four-layer stack accumulative roll bonding (ARB) process using AA1050, AA5052 and AA6061 alloy sheets is performed up to 2 cycles without a lubricant at room temperature. The sample fabricated by the ARB is a multi-layer complex aluminum alloy sh

Fabrication and Evaluation of AA6061/AA5052/AA6061/AA5052 Multi-Layer Complex Sheet by Cold-Roll Bonding Process

Autor: Seong-Hee Lee

Publikováno v: Archives of Metallurgy and Materials, Vol vol. 65, Iss No 3, Pp 1093-1097 (2020)

A cold roll bonding process is applied to fabricate an AA6061/AA5052/AA6061/AA5052 multi-layer sheet. Two AA6061 and two AA5052 sheets with 2mm thickness are stacked alternately to each other, and reduced to a thickness of 2 mm by multi-pass cold rol
