The continuous casting technology is a cost effective way to produce aluminium alloy sheet. As a result, aluminium alloys produced by this technology have great potentials to substitute steel in autobody panel applications. In the present work, fatigue tests were carried out on hot band (in as received and heat treated conditions) of a continuous cast AA 5754 aluminium alloy (4 mm thick) in directions of 0, 45 and 90° relative to the rolling direction. S-N curves of the alloy were measured in these directions. The alloy was produced using a twin belt continuous caster. The heat treatment on the alloy was conducted using both a batch anneal furnace at a slow heating rate (0.01°C s-1) and an induction heater at a fast heating rate (116°C s -1). The effects of heating/cooling rates during heat treatment on the fatigue anisotropy were studied in the alloy. It was found that induction heat treatment at 465°C greatly improved the tensile isotropy and reduced the fatigue anisotropy in this alloy.
