Mechanical properties and high temperature deformation behavior of al cu mg alloys microalloyed

Abstract

One of the prime research objectives in the area of structural materials for aircraft and space applications is to develop light weight alloys exhibiting high strength reasonable ductility high fracture toughness and good corrosion resistance properties In this respect Al alloys especially the precipitation strengthened wrought 2xxx 6xxx and 7xxx series of alloys have been investigated extensively Though the mechanisms of strengthening and toughening of these age hardenable alloys are now
