Architectured lightweight steel composite: evaluation of the effect of geometrical parameters and annealing treatments on deformation behavior

Architectured lightweight steel composites were designed and fabricated through the cold roll bonding (CRB) of stacked steel-aluminum sheet layers. The effects of geometrical parameters including thickness ratio (TR) and the number of constituent layers on bond strength and tensile properties of the...
