Sandwich-Like Cu/Al/Cu Composites Fabricated by Cryorolling

Journal Article


Abstract


  • Herein, sandwich-like Cu/Al/Cu composites are fabricated by hot rolling (300 ��C), cold rolling (25 ��C), cryorolling (���100 and ���190 ��C), respectively. Tensile tests are conducted and the fracture surfaces of both the Al and Cu sides are examined using scanning electron microscopy (SEM) for fractography and SEM-based energy-dispersive analysis. The microstructure of the composites is evaluated by optical microscopy and SEM. Results reveal that the highest ultimate tensile strength and the best ductility of the composites have been achieved using cryorolling of the rolling temperature ���100 ��C. Finally, discussion on grain size, bonding quality, and the thickness of the intermetallic layer between Cu and Al layers on the mechanical properties of the sandwich-like Cu/Al/Cu composites is focused.
