Dr Lai-Chang Zhang is an Associate Professor and the Program Leader Mechanical Engineering and Materials Engineering in the School of Engineering at Edith Cowan University. After receiving his PhD in Materials Science and Engineering at the Institute of Metal Research, Chinese Academy of Sciences in 2005, Dr Zhang held several positions at The University of Western Australian, University of Wollongong, IFW Dresden and Technische Universität Darmstadt. He focuses the research on the 3D printing (via selective laser melting or electron beam melting), titanium alloys and composites, and processing-microstructure-properties in high-performance materials (such as nanomaterials, ultrafine-grained materials and metallic glasses). He is one of leading scholars in 3D printing, especially in titanium alloys. His work in 3D printing has been leading in alloy development suitable for 3D printing, processing optimization, microstructure characterization, mechanical properties, fatigue properties and corrosion resistance properties. Many work has been published in Acta Materials, Corrosion Science, Electrochemica Acta. Due to his leadership in 3D printing of titanium alloys, he has published several invited review papers on selective laser melting or electron beam melting of titanium alloys.
