A Global Renaissance of Metallurgy: The Birth of Metallurgy 2.0

主講人 : Prof. Zhongyun Fan

Historically, the discovery, development and application of  ls have set the pace for the evolution of human civilisation. Today,  ls are the backbone of global manufacturing and the fuel for economic growth. However, extraction and processing of  ls are highly energy intensive and cause severe environmental damage:  l extraction accounts for 15% of global primary energy demand and 12% of global greenhouse gas emissions. The global grand challenge is to decouple economic growth from environmental damage. The worldwide sustainability crisis has led to a complete rethink of how we source, formulate and deploy  llic materials in the future, triggering a global renaissance of  llurgy and giving birth to  llurgy 2.0. In this context, we have developed a vision for full  l circulation (FMC), under which the global demand for  llic materials will be met by a full circulation of secondary  ls without the need for either mining or  l extraction. From a systems point of view, FMC can be delivered holistically through three effective approaches that correspond to 3 distinct research areas: (1) Closing the loop through liquid  l engineering; (2) Narrowing the loop by developing high performance and highly resilient  llic materials; and (3) Slowing down the loop by developing a unique  l health service (MHS) to extend the service life of  llic components. These research areas form the essence for sustainable  llurgy, denoted as  llurgy 2.0, which is characterised by secondary  ls (no more mining and  l extraction), multi-principle-element (MPE) alloys, generic longevity through liquid  l engineering, long component service life through the MHS. These directly contrast with conventional  llurgy (denoted as  llurgy 1.0), which is characterised by mining and  l extraction, primary  ls, single-principle-element (SPE) alloys, short component lifetime. In this talk, I will cover the following topics with specific examples:

·       Sustainability crisis from  l’s perspective.

·       The Concept of Full  l Circulation.

·       Liquid  l engineering to close the loop.

·       Developing high performance and highly resilient alloys to narrow the loop.

·       Developing the  l health service (MHS) to slow down the loop.

 Zhongyun Fan is a professor of  llurgy, the founder and current Director of BCAST (Brunel Centre for Advanced Solidification Techology) at Brunel University London. He is the principal investigator/director of the EPSRC funded LiME Research Hub, a national centre of excellence in liquid  l engineering. He is also the principal investigator for the UKRI Interdisciplinary Circular Economy Centre for Circular  ls. He has published over 400 scientific papers with an H-Index of 59 and a total citation of 14103 (Google Scholar). He has led a wide range of research projects as principal investigator with grants totalling over ￡70M. He chaired 6 major international conferences. He was the co-chairmen of the Casting and Solidification Society (IOM3, 2012-2018), is a Board Member of the Light  ls Division (IOM3), a Fellow of IOM3 and the Institute of Cast  l Engineers (ICME). He was the recipient of the Elegant Work Prize (1995), the Cook/Ablett Award (2003) and Dowding Medal and Prize (2012) of IOM3. Fan’s research has been focused on (1) understanding of early stages of solidification covering prenucleation, heterogeneous nucleation, Grain initiation and Grain refinement; (2) developing high performance  llic materials for closed-loop recycling; and (3) developing innovative techniques for extending the service life of  llic materials.
