- Abstract
- In this research, a series of secondary warm rolling was performed under various process conditions in order to evaluate the influence of thermo-mechanical treatment on the interface microstructure and subsequent mechanical properties of roll-bonded STS/Al/Mg 3-ply laminates. The variation of interfacial microstructure was observed by scanning and transmission electron microscopes equipped with energy dispersive X-ray detector. Uniaxial tensile, hardness and drum peel tests were then carried out to clarify major mechanical properties of STS/Al/Mg clad sheets. We revealed that annealing for 60 min followed by secondary warm rolling at 300 degrees C under the reduction ratio of 20% could effectively improve the bonding strength at the Al/Mg joint and the tensile properties of roll-bonded STS/Al/Mg 3-ply laminates.
