王贵高级研究员与David St John教授报告内容简介：
Wang Gui is a senior research fellow at DMTC, school of mechanical and mining engineering. After obtained his PhD at Tsinghua University in 1994,
he spent 6 years at the Beijing University of Aeronautics and Astronautics as a post-doctoral research fellow and then an associate professor in 1996
in the research group of near net shape casting technology of aircraft and aero-engine structures and rapid prototyping. He worked for QMI Solution as
a research and development engineer when moving to Australia in 2001, senior engineer at advanced moulding Technologies and BoCAR Automotive. He joined
UQ in 2008 as a senior research fellow. His primary research activities lie in micro/meso-scale manufacturing, Titanium alloys and processing for both
medical and aerospace application, aluminium alloy solidification.
Professor StJohn is a graduate of The University of Queensland with a BSc(Hons) and PhD in Physical Metallurgy. From 1994 to 2008 he was with the
CAST Cooperative Research Centre being CEO from August 2002. He initiated the Centre of Advanced Materials Processing and Manufacturing (AMPAM) at UQ
in 2009. He has over 300 publications in journals and conference proceedings with research interests covering a broad range of topics including grain
refinement and the formation of casting defects, in particular hot tearing. His work on grain refinement covers Al, Mg and Ti alloy systems which
enabled the verification of a new theoretical perspective on the mechanisms of refinement encompassed by the Interdependence Theory developed in 2011.
Prof StJohn was awarded the Materials Australia Silver Medal in 2011 for “outstanding contributions to the advancement of metallurgy, metallurgical
engineering, materials science or materials engineering through management, teaching, innovation, development or research”. His team was awarded the
ASM Henry Marion Howe Medal in 2006 for the best paper published in Metallurgical and Materials Transactions in 2005, and the Magnesium Technology
Award by TMS in 2003.郑州大学版权所有，禁止非法转载！2015-01-26 15:57:33
