Solution Heat Treatment, Forming and in-die Quenching (HFQ) and Superplastic forming (SPF) are attractive forming techniques in nowadays manufacturing industry field. Aluminium Lithium (Al-Li) alloy is one of the increasingly popular material used in the aerospace industry.
In order to form complex-shaped Al-Li components for aeronautic applications, SPF technology is usually used, which requires the simultaneous control of many critical parameters including: temperature, strain rate via applied gas pressure and blank holding force etc. HFQ as a new forming technology is a novel hot forming technology combining forming and heat treatment in one operation.
In the past years, the HFQ technology has been used to form a number of medium and high strength aluminium alloys, such as AA5XXX, AA6XXX, AA2XXX and AA7XXX. My research project is to investigate the feasibility of HFQ forming of Al-Li alloys. Additionally, the FE simulation of SPF process on Al-Li alloy is provided.
