Understanding and Design of Atomic-scale Distorted Lattice in High Entropy Alloys with Unusual Mechanical Properties

30 August 2019

The presentation was held at the Lecture Theatre of HKIAS’ new office.

On 29 August 2019, Professor Yong Yang, a Professor in Department of Mechanical Engineering of City University of Hong Kong (CityU), delivered a presentation titled “Understanding and Design of Atomic-scale Distorted Lattice in High Entropy Alloys with Unusual Mechanical Properties” for Hong Kong Institute for Advanced Study at CityU.

Lattice distortion in high entropy alloys (HEAs) is an issue of fundamental importance but yet to be fully understood. In the presentation, Professor Yang discussed the recent research dedicated to lattice distortion in HEAs with an emphasis on the basic understanding derived from theoretical modeling and atomistic simulations. In addition, the research findings showed that lattice distortion could be related to the phase transformation, dislocation dynamics and yielding in HEAs.

Professor Yang obtained his Bachelor degree in mechanics and economics (dual degree) from Peking University in 2001, MPhil degree from HKUST in 2003, and PhD degree in solid mechanics and materials science from Princeton University in 2007. His primary research interest is in the development and mechanical behavior of advanced structural materials, such as metallic glasses and high entropy alloys. His recent research also extends to mechanics of flexible electronics and hydrogels.
