Prof. LIN Jianguo of Imperial College London delivers distinguished lecture on hot stamping techniques

Prof. LIN Jianguo, Head and Professor in Mechanics of Materials Division, Department of Mechanical Engineering, Faculty of Engineering, Imperial College London, United Kingdom, delivered the 17th PAIR Distinguished Lecture titled “How to get high quality experimental data for hot stamping?” on 9 April 2024. The hybrid lecture attracted over 150 participants joining in person and online from more than ten countries and regions across Australia, Asia, Europe and North America. It was also broadcast live on multiple social media platforms, including YouTube, Weibo, Bilibili, etc., captivating an online viewing audience of over 12,400.

The lecture commenced with a welcome speech and speaker introduction by Ir Prof. MAN Hau-chung, Dean of Faculty of Engineering and Director of the Research Institute for Advanced Manufacturing (RIAM). In Prof. Lin presentation, he primarily indicated the increasing global requirements for reducing energy use and carbon dioxide emission of transportation vehicles, lightweight passenger cars have become an inevitable trend. Ultra-high strength steel (UHSS) can save the production cost of vehicles, improve productivity and car performance. Next, he introduced the “HFQ-Technology” developed by his team in recent years that has enabled high strength alloys to be stamped into complex-shaped automotive components. He outlined the use of thermomechanical experimental tests for generating high quality data for modelling, and the use of spatio-temporal method for determining necking and fracture strains of sheet metals. He also explained the computational steps for evaluating the formability of sheet metals under hot stamping. To conclude, Prof. Lin emphasised that improvements in experimental sciences, technologies and standardised testing are important for supporting the development of new materials processing technologies.

A question-and-answer session moderated by Prof. Man and Prof. FU Mingwang, Associate Director of RIAM, followed. Both the online and on-site audience engaged in a productive discussion with the professors.
