Investigation of Porous Defects in Spray Formed 7XXX Aluminum Alloy

Abstract:

In this work, Al-10.8Zn-2.8Mg-1.9Cu alloy was manufactured by the spray forming technique. The microstructure of the spray-formed alloy was investigated by optical microscopy and field emission scanning electron microscopy. The results indicated that the porosity in the spray-deposited alloy was mainly composed of interstices, interconnected pores and gas pores. The distribution and types of porous defects were different, responding to position of the preform.
