Guest Speaker：Prof. Anders E. W. Jarfors, Jönköping University,Sweden

Inviter: Prof. Liming Peng

Date&Time: Monday, 30 March, 10:00-11:30

Venue:  Yiucheng Lecture Hall（500）

Biography:

Anders E. W. Jarfors is a Swedish researcher in materials and manufacturing. He did his MSc and PhD at the Royal Institute of Technology in Sweden. He has worked at the Royal Institute of Technology in Stockholm and the Swedish Institute of Metals Research (formerly KIMAB and now RISE and Swerim). He has also worked at the Singapore Institute of Manufacturing Technology and MMI Holding Pte Ltd in Singapore. He was also an Adjunct Associate professor at Nanyang Technological University. He has held guest and visiting professorships in China with the China Academy of Machinery Sciences and Technology and at Nanyang Technological University, Singapore. He is currently a professor of materials and manufacturing at Jönköping University and a visiting professor in Sustainable Manufacturing at Cranfield University.

He has a long list of empirical work in materials science and manufacturing processes, ranging from metal casting and sheet metal forming to powder metallurgy and spray forming. The main research is on metal casting and automotive components. He is also an active teacher, and there is a need for a simplistic description of the foundations of a scientific approach.

Abstract:

The presentation deals with the complex matter of melt and material quality. Needs from materials users. It starts with the needs arising from the dramatic shift from conventional HPDC to automotive large-format castings. What is meant by Melt quality is defined. The issues arising from melting and handling, as well as mould filling, are discussed. The issues related to in-house returns and secondary aluminium are also treated from a quality and environmental perspective. All is summarised in a look forward and identifying the future challenges.
