Prof. Huang received his Ph.D. degree in 2012 from Mines ParisTech, France. He worked at NTNU and EPFL as postdoc from March 2012 to November 2017. He became a professor at XJTU since December 2017. Prof. Huang's main research interests include additive manufacturing, laser shock peening, as well as microstructural evolution during thermo-mechanical processing of metallic materials. His work has been published in prestigious journals including Prog Mater Sci, Acta Mater, Int J Mach Tools Manuf, Addit Manuf, Int J Plasticity (Google Scholar citation >3700, H-index=30, 2023 Elsevier most cited Chinese Researchers ) with 3 ESI highly cited papers.

Magnesium and its alloys, as a promising class of materials, is popular in lightweight application and biomedical implants due to their low density and good biocompatibility. Wire Arc Additive Manufacturing (WAAM) is a revolutionary technology that realizes intelligent stacking of materials through digital control, which demonstrates great potential in preparing large-format magnesium alloys. This presentation aims to showcase our recent progresses in wire arc additive manufacturing of magnesium alloys, including process optimization, customized heat treatment process exploration and the corresponding microstructure evolution and mechanical properties. 

Dr. Shang Sui is an associated professor in Xi’an University of Technology. He received his PhD degree in Materials Processing Engineering in 2019, and then worked in Singapore Institute of Manufacturing Technology for two years. He specializes in Additive Manufacturing of Metallic Materials, including nickel-based superalloys, titanium alloys and magnesium alloys.

Metamaterials are artificial structures that can be flexibly designed to achieve special physical properties from the microscale to the macroscale. The geometrical foundation of microlattice metamaterials originates from the study of atom lattices, which are periodically arrayed by interconnected units with connecting struts and custom pores. In the microlattice metamaterials, the struts determine the mechanical strength, while the pore size distribution influences fluid/gas transport. Today, bionics allow microlattice metamaterials to achieve superior physical properties by mimicking natural shape, performance, and function. Therefore, by combining the bionic concept and lattice topology, and using 3D/4D printing technology, robust and high-throughput transport architectures can be realized for lightweight engineering, bio-scaffold engineering, and environmental engineering.

ZHANG Lei, a postdoctoral fellow at City University of Hong Kong & Huazhong University of Science and Technology (Team of Academician LU Jian, team of Professor SHI Yusheng and SONG Bo), and a Hong Kong Scholar (2022), has been conducting research on the design of lattice porous structures and additive manufacturing. He has published more than 30 SCI papers in high-level international journals such as Nature Communications, International Journal of Extreme Manufacturing, Acta Materialia, Acta Biomaterialia, including 11 as the first author, with more than 1,100 SCI citations and an H-index of 17. He serves as a guest editor of journals such as Biomimetics. He has more than 10 authorized invention patents and edited 2 monographs in Chinese and English. He has presided over national/provincial and ministerial projects such as the National Natural Science Foundation of China Youth Fund Project and the Hong Kong Scholar Project of the Ministry of Human Resources and Social Security.
