Plenary Speakers



Emeritus Prof. Druce Dunne,
University of Wollongong, Australia

 

Druce Dunne retired from the University of Wollongong in New South Wales, Australia in 2003, after an academic career spanning more than 30 years. He was the Professor and Head of the Department of Metallurgy for 10 years, as well as the initiator and leader of major research centres based on advanced materials and welding and joining. In 2004 he was made an Emeritus Professor of the University and was awarded a DSc degree based on his outstanding research contributions on martensitic transformations and shape memory alloys, as well as welding and thermomechanical processing of steels. Although part of his research has been concentrated on fundamental aspects of physical metallurgy, he has also worked in close collaboration with the local steel industry on applied research projects. He has maintained a strong interest in martensitic transformations in steels and non-ferrous alloys since he completed his PhD project on the crystallography of martensitic transformation in steels in 1968. Subsequent research work as a Post-Doctoral Fellow at the University of Illinois led to the discovery of thermoelastically reversible martensitic transformation in an Fe-Pt alloy and the first recorded case of a shape memory steel. Visiting Professorial positions at the University of Cambridge, the Catholic University in Leuven (Belgium), Tsukuba University in Japan and INSA de Lyon in France have stimulated his extensive research output on fundamental and practical aspects of shape memory alloys.

 

Speech Topic: Shape Memory Steels

Speech Abstract: Iron-based shape memory alloys have been studied extensively over the past several decades because of their promise of providing low cost materials for applications that include heat-shrinkable couplings, vibration damping devices and sensing/activating components. Although several practical applications have been reported, particularly for Fe-Mn-Si-based alloys, shape memory steels have not generally achieved the performance levels demonstrated for Ti-Ni and Cu-based alloys. Nevertheless, there have been some recent reports of improved shape memory properties for complex multi-component ferrous alloys containing Ni, Co, Al, Ta and B. This presentation reviews this work and other alloy developments designed to improve the shape memory properties of ferrous alloys. The overall aim is to define alloying and processing strategies that can lead to new alloy steels with shape memory properties that are competitive with those of non-ferrous shape memory alloys.
 

 

 


 

Assoc. Prof. Huijun Li,
University of Wollongong, Australia

 

Prof Huijun Li obtained a PhD degree in 1996 from the University of Wollongong; He has 20 years research experience in materials science and engineering.

He has published 4 book chapters and more than 300 papers over his career in the field of welding metallurgy, new alloy development, surface engineering, nuclear materials and microstructure characterization.
 

In 1995, he joined CRC Materials Welding and Joining as a postdoctoral research fellow at University of Wollongong. In 2000, he took a research scientist position at Materials Division, ANSTO (Australian Nuclear Science and Technology Organisation), he worked on a wide range of research projects in conjunction with the CRC Welded Structures, CRC CAST3, CRC Rail, British nuclear research organisations and American national laboratories. During this period, Prof Li pioneered research on 9-12% Cr creep resistant steel s in Australia. Prof Li started working at University of Wollongong from July 2008; he is heavily involved in research work with Defence Materials Technology Centre (DMTC), Energy Pipeline CRC (EPCRC), Baosteel Australia Joint Centre (BAJC), and Australian Rail Industry.
 

Prof Li has been supervising (or co-supervising) 28 PhD students and 10 postdoctoral fellows; he is the chief investigator of 26 research projects supported by DMTC, EPCRC, BAJC, Australian Research Council (ARC) and other industry sectors. He was involved in the preliminary work on the production of engineering components of Titanium alloys using one such method of additive manufacture, namely gas tungsten arc (GTA) welding with mechanised wire addition. He then proposed to produce intermetallics with twin wire system, combining the concept of additive manufacturing and in-situ alloying with GTA process. Gamma TiAl has been successfully produced with this method.

 

Prof Li was awarded Australian Museum Eureka Prize for Outstanding Science in Safeguarding Australia, 2013, Australia Endeavour Fellowship 2014, and Defence Materials Technology Centre-Capability Improvement Award in 2014 and 2016.

 


 

Prof. Dongyun WAN,
Shanghai University, China

 

Dr. Dongyun WAN is a Professor of School of Materials Science and Engineering of Shanghai University, China. She obtained her Ph.D. degree at Institute of High Energy Physics, Chinese Academy of Sciences (CAS) in 2004, and became a full professor in Shanghai University in 2014. She worked as a postdoctoral fellow at French National Center for Scientific Research (CNRS) from 2004 to 2006, and was an associate professor (2007-2012) and professor (2012-2014) in Shanghai Institute of Ceramics, CAS. Her research field is functional thin solid films (Graphene and VO2, et al.) and their energy-conversion and energy-saving applications. She has published more than 60 papers in the national and international journals(Times Cited by Science Citation Index: 1788, H-index: 24, up to the end of 2016) and got more than 20 national patents (12 of which have been authorized).

 

Speech Title: High Performance VO2 Thin Film: Preparation, Optical and Electrical Properties, and First-Principles Study


Speech Abstract: Thermochromic smart windows are considered attractive because they are visibly transparent and can intelligently control the amount of solar heat (mainly in the near-infrared region) in response to changes in ambient temperature. VO2, which undergoes a metal-insulator transition (MIT) at a critical temperature Tc (68 oC for bulk VO2), has attracted much attention as a thermochromic material for use in smart windows. Also, it exhibits potential as a unique thermal sensing material in uncooled IR detectors due to its excellent resistance properties, suitable thermal times constanct τ, low 1/f noise, and high temperature coefficient of resistance (TCR). Herein, we are going to report our latest results of controllable preparation of high-performance VO2 films like autonomous phase regulation derived from a “sandwich” structure design, high TCRs and enhanced conductivity by strain controlling with the exclusive two-dimensional octahedral structure, and low temperature fabrication by low-pressure chemical vapor deposition. Through novel design of film system and effective microstructural controlling, the performances of VO2 material are hope to be greatly improved and the cost to be controlled. These have provided new ideas for enhancing the performance of VO2 thin film and may promote its intensive applications in the energy-saving smart-windows and IR detectors.
