Abstract:
According to the principle of accumulative roll bonding(ARB),the 20 ply clad sheet from
austenitic stainless steel (STS304)/pure aluminum(Al1060)/aluminum alloy(Al3003) …/ austenitic
stainless steel (STS304)sheets with excellent heat, anti-corrosion and mechanical properties of
stainless steel and the high thermal and electrical conductivities of aluminum was fabricated by
accumulative clad rolling (ACR). Well-bonded clad plate was successfully obtained in the procedure:
Al1060 sheets with a thickness of 0.5mm and Al3003 sheets 0.5mm thick and STS304 sheets 0.5mm
thick were employed. Basic clad sheet from different ply Al1060/Al3003 sheets was obtained with an
initial rolling reduction of 44% at 450°C followed by annealing at 300°C, then ACR was with
reduction of 50% at 550°C from STS304 on each side. The stretch property, bonding property,
microscopic structure and interface composition were measured and analyzed. It was indicated that
the best clad sheet had bonding strength of 129MPa and stretch strength of 225MPa. At the
end,STS304 sheet with thickness of 3mm was taken the place of the clad sheet from STS304 sheets of
1mm and Al1060 of 1mm and Al3003 of 1mm. Therefore, it decreased by 44% in weight and
economizes rare metal elements Cr and Ni of 66% in weight.
