Multilayer composite Al99.99/AlMg3 sheets prepared by accumulative roll bonding

Original language description

Accumulative roll bonding (ARB) allows producing ultrafine-grained sheets of high strength and has been successfully used to prepare such materials from aluminium alloys. However, due to intensive work hardening of bond-rolled AlMg3 sheets, significant edge cracking occurred. Cracking was reduced by cladding AlMg3 with aluminium. Lamellar composites were thus prepared. Their structure was studied by EBSD and TEM; hardening was monitored by hardness measurements and tensile tests. Composite grain sizes are coarser and high angle grain boundaries fraction is lower than in mono-material sheets. In accordance, the evolution of strength with ARB cycles in both materials differs. AlMg3 composite layers exhibit less work hardening than the mono-material; composite strength is between that of the two mono-material ARB sheets.
