Development of an accurate neuronal material model for aluminum alloys would facilitate better process control and parameter optimization in the aircraft industry. This research primarily attempts to design a connectionist constitutive model for aluminum 7075 alloy using multi-layer perceptrons. The backpropagation algorithm is used to train the designed network whose performance is then valida...

Aluminum alloy 7075 (Al 7075) has been widely used in aerospace and automotive industries to replace heavier alloys. This is because of its superior properties high specific strength, corrosion resistance, good formability, recyclability low fabrication cost. However, the ductility heat generation during drilling Al often produces a burr at entrance exit workpiece surface. research investigates...

Aluminum 2024 and 7075 alloys which are widely used in aerospace and marine applications were chosen to investigate their strengthening mechanisms. Using differential thermal analysis (DIA), metallography and tension tests, the best solutionizing conditions were determined to be 500±5°C and 2 hours for 2024 and 480?±5°C and 1 hour for 7075 alloy. Aging was performed in the range of 100 to 200°C...
