Effect of thermal treatment on the interfacial shear toughness of an aluminium composite laminate
The microstructure and mechanical properties in the interface region of a
multilayer composite laminate based on Al-Zn (Al 7075) and Al-Cu (Al 2024) alloys
have been mainly characterized by EBSD and shear tests. It is shown that varying
solution heat treatments affect the microstructure of the constituent aluminium alloys in
the bonding region and, as a consequence, the interfacial mechanical properties. The
increase in the solution treatment time improves the interfacial toughness of the
multilayer aluminium laminate due to higher intrinsic toughness of the constituent
aluminium alloys.Financial support from CICYT (Project MAT2003-01172 and MAT2006-11202)
