Influence of constituent materials on the impact toughness and fracture mechanisms of hot roll-bonded aluminum multilayer laminates

Two aluminum multilayer laminates have been processed by hot roll bonding following similar processing paths. The first one is constituted by alternated Al 2024 and Al 1050 layers (ALH19) and the second one by alternated Al 7075 and Al 1050 layers (ADH19). The influence of the constituent materials...
