Professor Chunlei Qiu is a Professor and Ph.D. supervisor at Beihang University. He received his Ph.D. in Metallurgy and Materials from the University of Birmingham, UK, in 2010. From 2011 to 2016, he worked as a Research Fellow at the University of Birmingham, and from 2016 to 2017, he served as an Assistant Professor in the School of Engineering at Cardiff University, UK.
Over the past decade, Professor Qiu has focused on advanced near-net-shape forming technologies, including laser additive manufacturing (AM), hot isostatic pressing, and hot extrusion. His research has extensively covered the formability, laser-material interactions, solidification behavior, defect formation and suppression mechanisms, microstructural evolution, and mechanical properties of titanium alloys, superalloys, aluminum alloys, high-entropy alloys, titanium aluminides, Invar alloys, stainless steels, and refractory metals. He has made breakthroughs in stress deformation and defect control in laser additive manufacturing of large aerospace titanium alloy components, successfully fabricating multiple large-scale aerospace parts and structures. His work also enabled the additive manufacturing of various difficult-to-form high-performance aluminum and high-entropy alloys, and the development of novel high-strength, high-toughness titanium, aluminum, and high-entropy alloys with fully equiaxed grain structures.
As a key researcher, Professor Qiu has participated in several major UK and EU projects on near-net-shape forming and metal additive manufacturing, collaborating with leading aerospace companies and institutions such as Rolls-Royce, BAE Systems, Safran, Airbus, Thales, the European Space Agency, the Beijing Institute of Aeronautical Materials, and COMAC. As a principal investigator, he has led national key R&D programs in China and contributed to projects of the Fundamental Research Center for Aero-Engine and Gas Turbine. He holds one U.S. patent, one UK patent, and six Chinese invention patents.
This special issue aims to provide a platform for studies on additive manufacturing of various metallic materials which have played a crucial role in human industry and civilization. Novel fundamental research work on the laser/electron beam-material interaction, melt flow behaviour, defect formation and inhibition mechanisms, novel metallurgical phenomena, microstructural evolution mechanisms, residual stress and strain development and process-microstructure-property relationships of the additively manufactured metallic materials are all welcome. New advancement in additive manufacturing technologies and materials is also encouraged to be submitted to this special issue. The issue seeks manuscripts in the form of research papers, or review articles or perspectives.
