Present work aims to achieve high welding speed during friction stir of lightweight battery trays in the electric vehicle industry. This study reports high-speed (HSFSW) up 4.0 m min−1 AA6063-T6 alloys. The defect-free HSFSW joints are produced by adopting aggressive material mixing, i.e. higher tool rotation and plunge force. weld cross-section reported an unusual hardness profile ‘U’ shape in...

Automotive crash boxes require a material selection with strength and ductility in balanced combination. In this work, the behaviour of double-chamber AA6063 AA6082 aluminium profiles subjected to quasi-static dynamic axial crushing was studied experimentally. The were stretched two different levels between extrusion artificial ageing temper T6. higher pre-stretch resulted more ductile slightly...
