Brief BiosketchDr. XS Yang received his B. Eng. degree in Mechanical Engineering and Automation, and M. Eng. degree in Materials Processing Engineering from South China University of Technology (SCUT). He received his Ph.D degree in Mechanical Engineering in 2014 from The Hong Kong University of Science and Technology (HKUST). After that, he continued his research career at HKUST and PolyU, respectively. He joined the Department of Industrial and Systems Engineering (ISE) at The Hong Kong Polytechnic University as an Assistant Professor in 2017.
Dr. Yang’s research specialties are mainly to atomic-scale dissect the processing-structure-property relationship of nanostructured materials. He is carrying out the research topics related to the atomic understanding (HRTEM, In-situ HRTEM, theoretical modelling, and atomistic simulations) of the microstructural evolution, phase transformation, and plastic deformation mechanisms of high-performance heterogeneous nanostructured materials (copper alloys, magnesium alloys, high-entropy alloys, and steels, etc.) fabricated by thermomechanical techniques, laser processing or 3D printing, and Ultra-precision machining technology, etc. His research works were published in top specialized journals, such as Acta Materialia, International Journal of Plasticity, Scripta Materialia, and Journal of the Mechanics and Physics of Solids, etc., etc.
