Abstract

The mechanical properties of 7xxx series alloys can be tailored by subjecting them to deformation processing and heat treatment. In the present study dealing with spray forming of 7055 AA, extrusion and heat treatment involving solutionizing followed by peak aging resulted in improved mechanical behavior. The strength and ductility obtained are comparable to that of extruded and heat treated as-cast 7055 AA (Mondal et al., 2011) [1]. Spray forming offers an alternate route to develop high strength aluminum alloys and the current study is an attempt that draws closer to the target value of 1GPa strength and 10% ductility for high strength aluminum alloys.
