**About the Editors**

### **Pan Gong**

Pan Gong, Ph.D., is an Associate Professor of Materials Processing Engineering at Huazhong University of Science and Technology in Wuhan, China. His current research interests broadly centre on bulk metallic glasses, high-entropy alloys, titanium alloys, metallic composites, precision metal plastic forming, powder metallurgy, and incremental sheet forming. He teaches professional courses such as Materials Forming Equipment and Automation, Fundamentals of Precision Plastic Forming, and Stamping Technology and Mold Design at the School of Materials Science and Engineering. He obtained a PhD in Mechanical Engineering from Tsinghua University, and both BSc and MSc degrees from Huazhong University of Science and Technology.

#### **Maojun Li**

Maojun Li, Ph.D., is an Associate Professor of Precision Manufacturing at Hunan University in Changsha, China. His current research interests broadly centre on the machinability of advanced aerospace alloys and composite materials, microscale machining, the development of novel/innovative processes (e.g., hybrid machining, high-power fibre laser cutting, ultrasonic-assisted machining, etc.), CFRP/Al joints, and computer numerically controlled (CNC) operation of machine tools including five-axis machining and industrial robots. His work has a strong materials element, particularly in relation to studying the effect of cutting variables on workpiece surface integrity and their subsequent influence on the in-service performance of parts. Many of his research activities involve strong industrial collaboration and relevance. He obtained a PhD in Mechanical Engineering from University of Birmingham, UK, and both BSc and MSc degrees from Huazhong University of Science and Technology.
