Extrusion of Lightweight Aluminum and Magnesium Alloys Structures for Aviation Applications

The development of light-weight materials and fabricating parts/sub-assemblies substantially large dimensions has become a major issue for the aerospace industry, which boosted more advanced with high specification properties. Recent aluminum magnesium alloys developments are based on achieving superior fatigue crack growth resistance, better corrosion lower density, etc. Standard manufacturing techniques, such as extrusion, ought to be developed in order find beneficial solution allowing structural weight reduction, is very efficient means improving aircraft performance. It associated problem extrusion profiles complex cross-section shape. In this work formability process was determined by upsetting test through flow stress relationship deformation size rate. results Al (7075, 2024, 8090, 2099) Mg ( AZ31, AZ61, AZ80, WE 43) were used determining conditions various cross section shape ratio. analysis macro microstructure extruded products their mechanical properties demonstrates strong influence extrudate metal exit speed force value. Macro-and all investigated after highly homogeneous terms grain morphology phase components, compared macro- initial state, justifies use them production aviation profiles.
