Topic：Brittle Failure of Boron Carbide and Related Materials from Atomistic Simulations; Strategy to Improve Ductility
Time：08：30AM, Oct. 31st (Monday)
Ceramics such as boron carbide (B4C) are strong but too brittle for extended applications. The development of B4C based materials with improved properties is prevented by their complex bonding conditions and their relationships to the macroscale mechanical properties. In this talk we will discuss the deformation and brittle failure mechanism of B4C from atomistic simulations. We first identified a unique deformation path shearing along the most plausible slip system of (01
Qi An is an assistant professor in Chemical & Materials Engineering Department at University of Nevada, Reno (UNR). He joined UNR in July 2016. Before then, he was a postdoctoral scholar in the Division of Chemistry and Chemical Engineering at Caltech. Qi An received his B.S. from University of Science and Technology of China, and his Ph.D. in Materials Science from Caltech in 2012. His research area is computational materials science. His research specifically focuses on material properties under extreme conditions; deformation and failure mechanism of superhard ceramics, metallic glasses, metals, and thermoelectric materials; detonation and sensitivity of energetic materials; and surface chemistry. He has authored or co-authored over 60 publications in the peer-review scientific journals.
