Microstructural and Mechanical Evaluations of Spray-Deposited 7XXX Al-AlloysAfter Conventional Consolidation

摘要

Alloys of the 7XXX type were prepared using the spray atomization-depositionmethod. These alloys were also hot extruded and subsequently heat treated at different temperatures. Microstructural characterization of the alloys was carried out by transmission electron microscopy and X-ray diffractometry. The mechanical properties were assessed through tensile tests using an Instron machine. jg.
