Technical-economic evaluation of severe plastic deformation processing technologies—methodology and use case of lever-arm-shaped aircraft lightweight components

Particle-Reinforced Aluminum Matrix Composites (AMCs)—Selected Results of an Integrated Technology, User, and Market Analysis and Forecast

“…yield strength of powder-metallurgically produced AMCs, Table 1) represents a doubling of the value. Based on a constant component strength, a reduction of the material cross-section by 50%, a corresponding saving of material quantity, as well as weight reduction of 50% are enabled by the usage of powder-metallurgically produced AMCs [5,25]. These potentials might (over-)compensate the disadvantage of a lower elongation.…”

“…As outlined before, it can be assumed that an increase of 50% in yield strength enables savings in material quantities of approx. 50% and, thus, weight reductions of the same ratio [5,25]. It can be stated that the improved yield strength of the material allows for achieving other user requirements regarding quality (e.g., stability and durability) of a specific aircraft component with a reduced material thickness [25].…”

“…50% and, thus, weight reductions of the same ratio [5,25]. It can be stated that the improved yield strength of the material allows for achieving other user requirements regarding quality (e.g., stability and durability) of a specific aircraft component with a reduced material thickness [25]. In the following, calculations of monetary effects of weight reduction will be demonstrated.…”

“…For example, monetary consequences of a changed geometry of components for aircraft construction could be considered as additional costs of the development and manufacturing phase. Additionally, a reduced material cross-section because of the higher yield strength potentially causes lower material quantities which are needed for producing a specific number of aircraft components [25]. Resulting cost-saving effects regarding the material costs should also be addressed by further analyses.…”

Experimental and numerical prediction of extrusion load at different lubricating conditions of aluminium 6063 alloy in backward cup extrusion

“…In contrary to conventional hot extrusion, this research work investigates how different lubricants at a temperature below recrystallization temperature can be used to predict extrusion load by increased strain hardening and grain refinement. The plastic deformation process during cold extrusion for technical-economic evaluation of materials can be found in (Herold et al, 2018) and the isothermal extrusion using the surface formation of the extrudate and flow pattern of material methods (Peng & Sheppard, 2004).…”
