Bimetal or laminated metal composites consisting of several metal or alloy layers can efficiently absorb the advantageous properties of each metal when utilised as raw materials for future remanufacturing. Their mechanical response characteristics and failure modes face uncertain challenges during the processing owing to the existence of heterogenous interfacial transition zones between layers. This work aims to study the uncertainty quantification in bending processing of a novel bimetal compos...

The interfacial zone formed in the manufacturing process of bimetal or laminated metal composites owes complicated microstructures and properties. This special feature greatly affects the fracture toughness and fatigue strength of metal composites. The crack growth behaviours, from a weak layer (AH36 carbon steel) to a strong layer (2205 duplex stainless steel), at the interfacial zone of a hot-rolled bimetal composite (2205/AH36 BC) were investigated. To clarify the potential factors altering t...

Laminated/bimetal composites can offer the advantage of combining constituent metals, but their heterogeneous microstructures exhibit different mechanical properties during subsequent remanufacturing process than those of the homogeneous counterparts. This study investigated the tensile properties, microstructural evolution and deformation behaviours of a new explosive welded TA1/5083 composite sheet using the in-situ characterisation. It is found that a wavy transition zone forms in the composi...
