研究领域

Prof Wu’s research interest is in the development of aerospace materials, in particular Ti alloys, and their manufacturing processes. Her key activities include: developing new alloys for specific applications; modifying existing alloys or processing conditions to maximise their performance, characterising microstructure and mechanical properties of Ti alloys in a range of sizes and developing new manufacturing processes to reduce manufacturing costs, whilst meeting mechanical property requirements for individual service conditions. Professor Xinhua Wu has been involved extensively in Ti and TiAl alloys and in advanced powder processing, in particular for Ti and Ni alloy powders. Her research into alloy developmentand characterisation coversa range of Ti alloys (Ti64, Ti6246, Ti-15-3, Ti-15-3-0.1C, BuRTi, Ti5553…), TiAl (Ti4522XD, Ti46Al8Ta…), NiTi and NiTiCu shape memory alloys, NbSi ultrahigh temperature alloys etc.Her recent activities are mainly on development of innovative manufacturing including laser additive manufacturing and net-shape HIPping (hot isostatic pressing) which are technologies able to produce 3D complex components from their computer designs in one step, thus lead to a reduction in current manufacturing cost by 30-50% and reduction of material wastage by 90% and reduction of lead-time from 24 to 3 months for Ti, Ni, Al and steel structural components.
