Summary of Interests

Metal additive manufacturing (AM) revolutionises the industrial practice of numerous applications in automotive, aerospace, energy and even biomedical sectors. Understanding of the AM materials is key to unlock the potential of the metallic materials to be applicable successfully via improving additive manufacturability of legacy alloys using innovate processes and designing some novel AM alloys for some specific uses. Computational modelling taking into account the intrinsic property together with the AM process science enables a science-pushed design tool to be established for searching and assessing the ability to additive manufacturing in metallic materials such as nickel-base superalloys, and titanium alloys. This is to exploit my 10-year research expertise in developing predictive capability for advanced manufacturing processes – investment casting, laser/electron beam fusion welding and AM.
