Chunlei Qiu is a professor and a doctoral director at the School of Materials Science and Engineering, Beijing University of Aeronautics and Astronautics (BUAA). He received his Ph.D. degree from the School of Metallurgy and Materials, University of Birmingham, U.K., in 2010, and was a researcher at the University of Birmingham from 2011 to 2016, and an assistant professor at the School of Engineering, Cardiff University, U.K., from 2016 to 2017. He has been mainly engaged in the research of advanced near-net forming technologies, including laser additive manufacturing and hot isostatic pressing near-net forming, for the past ten years or so. He has carried out a lot of research work on laser additive manufacturing formability, laser material interaction, solidification behavior, defect formation mechanism, microstructure evolution law and mechanical behavior of titanium alloys, high temperature alloys, aluminum alloys, high entropy alloys, titanium-aluminum alloys, Invar alloys, stainless steels and refractory metals. He has made breakthroughs in laser additive manufacturing of large-scale aerospace titanium alloy structural components in terms of stress deformation and defect control, and successfully prepared many large-scale aerospace components and structural parts, and made breakthroughs in the additive manufacturing of a variety of difficult-to-form high-performance aluminum alloys and high-entropy alloys, and developed a variety of new types of high-strength and high-plasticity titanium alloys, aluminum alloys, and high-entropy alloys with fully isometric crystalline tissues. As a principal investigator, he has participated in several major near-net forming and metal additive manufacturing projects in the UK and EU, and has carried out collaborative research with major aerospace companies and organizations at home and abroad, such as Rolls-Royce (UK), BAE Systems, Safran (France), Thales, Euronavigation, and Beijing Institute of Aeronautical Materials (BIAM). He was selected as one of the "Thousand Talent.
