Yang Zhong, a fourth-year graduate student from Professor Leon Shaw’s group who is currently doing his thesis research focused on the simultaneous improvement of hardness and fracture toughness of WC-Co material, has been awarded one of ten Graduate Excellence in Materials Science (GEMS) Awards by the Basic Science Division of The American Ceramic Society.
The GEMS awards “recognize the outstanding achievements of graduate students in Materials Science and Engineering” and are open to all graduate students who make an oral presentation in any symposium or session at the annual Material Science & Technology (MS&T) Conference. Zhong presented his research on “Sintering and Characterization of Nano-WC Co Powder – On the Formation of WC Platelets” at the 2011 MS&T Conference held in Columbus this past October.
Zhong has been working with Prof. Shaw to study the influence of processing and microstructure on the mechanical properties of WC-Co in the last 2 years. They have developed a process for the production of WC-Co with outstanding hardness and fracture toughness. They have also published 3 papers in Acta Materialia, Ceramics International and Journal of Materials Science on the synthesis and microstructure control of WC-Co.
