Tingkun Liu

Tingkun LiuTingkun Liu is a second year graduate student in the Materials Science and Engineering (MSE) Department at the University of Tennessee, Knoxville. Mr. Liu previously received his M.S. from Beijing Institute of Technology in 2013. While obtaining his master’s degree, Mr. Liu worked on micro mechanical properties of single crystal alloys and residual stress measurements in metallic materials using X-ray diffraction. Mr. Liu worked as an assistant researcher in Shanghai Synchrotron Radiation Facility, Shanghai Institute of Applied Physics in 2013 and 2014 and  22 Annual Report continued his research on residual stress measurements using synchrotron X-ray diffraction.

After joining Prof. Yanfei Gao’s group, Mr. Liu is focusing on the experimental and computational studies on mechanical behaviors of metallic alloys and bulk metallic glasses (BMGs). In his simulation study, finite element crystal plasticity analysis has been conducted to study the evolution of lattice strain under uniaxial loading in a representative volume element (RVE) using the commercial software package ABAQUS. In the spring of 2016, Mr. Liu served as a graduate teaching assistant for the undergraduate course “Introduction to Materials Kinetics Transformation Phenomenon.” Additionally, Mr. Liu participated in a research project at Oak Ridge National Lab (ORNL) that focused on studying the deformation behaviors of high entropy alloys (HEAs). The complete texture of a NiFeCoCrMn HEA after plastic deformation was measured by neutron diffraction at the Spallation Neutron Source (SNS). Electron back-scattering diffraction (EBSD) was used to investigate the microstructure and gain orientation changes during plastic deformation. Future research will concentrate on the relationship between the mechanical properties and structure in BMGs.
