Seminar Title: Fast Forming of Lightweight Components and Heat Transfer during Forming

Abstract

This seminar introduces the research of Dr. Xiaochuan Liu on hot stamping of lightweight materials and heat transfer coefficient. He has three main research achievements: Hot stamping of high strength aluminium alloy panel components with complex structures; Determination and modelling of the heat transfer coefficient for lightweight materials; Development of a smart forming information platform. Several hot stamping projects were completed during his research period, including forming of headlamp supports on high-speed trains, wing stiffeners on airplanes, middle channel reinforcement and B-pillars on vehicles. These projects covered the selection of materials, characterization and modelling of material properties, finite element simulations, design of forming tools, experimental validation and optimisation of processing windows. Meanwhile, he realized the importance of the heat transfer coefficient to the hot stamping and then made great efforts on its study. Firstly, a dedicated experimental setup and facility were designed and developed. The effects of contact pressure, tool material, lubricant, coating and temperature on the heat transfer coefficient were subsequently identified and modelled. By the research on hot stamping and heat transfer, his research group developed a smart forming information platform, which integrates essential information, and then guides and optimises the forming processes.

Resume

Dr. Xiaochuan Liu received his PhD degree from Mechanics of Materials Division at Imperial College London in 2019, with research experience in hot stamping of lightweight materials and determination of the heat transfer coefficient. He received 1^st Class BEng degree from the University of Sheffield in 2014 and 1^st Class MSc degree from Imperial College London in 2015 respectively. During his research period, Dr. Liu joined 4 international research projects, published 19 articles and obtained 2 international patents in total, of which 3 international research projects were as the principal (second) researcher, receiving a total funding of approximately £2.55 million, 4 SCI journal articles (Q1) were as the first author and 4 top international conference articles were as the first author.
