Fabrication of Aluminum alloy 2219 by using Stir Casting Process and Comparison of Micro structural and Mechanical Properties of Alloy 2219 with the Industrial based fabricated Alloy

Mechanical Engineering

High strength aluminum alloys have been used in aircraft and space industries for many years due to its supplementary advantages. Alloy commonly used as an aerospace material due to its characteristics such as excellent weld ability as well as weld strength. The optimum strengthening of Al is achieved by varies fabrication methods and heat treatment processes. The present work is to develop the aluminum alloy 2219 by adding different chemical composition. Stir casting process has been used to fabricate the alloy 2219 by taking weight percentage followed by forging operation with 400 kg of forging load. Then the specimens are heated in muffle furnace and these specimens treated in solution followed by aged to 240oC ,270oC and 310oC. After heat treatment the specimens have been analyzed in micro structural and mechanical tests, these properties have been studied on heat treated specimens to compare these results with the parent aluminum and aluminum alloy which is fabricated by the industrial methods.
