Reviews on the Forming Process of Heat Treatable Aluminium Alloys

Abstract

Available forming process applied for heat treatable aluminium alloy were reviewed and presented in this paper. The reviews emphasized on the heat treatment, application and contribution of the forming methods. Forming methods discussed includes traditional, warm forming, hydroforming, superplastic forming, hot forming with in-die quench (HFQ) and hot press forming (HPF). The effects of forming processes towards heat treatable aluminium alloy were presented through the understanding on each process strengthening phenomena and the heat treating phenomena. These were to ensure better understanding on heat treatable aluminium alloy composition changes throughout forming process. Finally, concluding remarks the underline challenges of forming heattreatable aluminium alloy and subsequently highlights the potential work that can be applied in order to ensure a more efficient and sustainable manufacturing agenda for heat treatable aluminium alloy.

Recent Developments and Future Challenges in Incremental Sheet Forming of Aluminium and Aluminium Alloy Sheets

“…During SMF, the sheet is deformed by exceeding the yield stress of the material [20]. The disadvantage of conventional methods of sheet metal forming is the need to manufacture special tools adapted to the shape of the element; therefore, the use of conventional SMF methods with the use of stamping dies is suitable for medium-and large-scale production [21,22].…”

An Overview on Forming Process and Heat Treatments For Heat Treatable Aluminium Alloy

“…Application of high strength aluminium alloy had been regarded as one of the most promising possibilities and applying this high strength aluminium alloy provide a very positive response in many requirements [1]. The average total aluminium content per car recorded in 2012 for European cars was 140kg with analysed distribution as follows [2][3][4].…”
