RESEARCH EXPERIENCE
University of North Carolina at Charlotte, Charlotte, NC
Research Assistant: (Dynamic Behavior of Advanced Materials Lab, 2008-present).
Experimental and numerical analysis of bulk metallic glasses over a wide range of strain rates and temperatures:
Successfully build up the heating unit for Kolsky bar system, and reduced the cold-contact time to 20 ms. Investigated the deformation mechanism of bulk metallic glasses (Brittle material) with mechanical testing method over a wide range of temperatures and strain rates. Using ABAQUS perform finite element analysis of the mechanical behavior of the materials. Found the transition from inhomogeneous to homogenous deformation when temperature was close to the glass transition temperature. Used Kolsky bar, MTS mechanical test system, Nanoindentation, TEM, DSC, OriginLab, and ImageJ.
Investigated the strengthening, failure behavior and microstructures of bimodal Cryo-milled Titanium:
Fabricated bimodal Titanium samples through a bottom up method. Statistically analyzed the grain size distribution within the samples using TEM, EBSD and OriginLab. Found remarkable improvement of the mechanical properties compare to the commercial pure Ti with MTS and Kolsky bar system. Applied SEM and TEM to perform the failure analysis of those samples.
Studied the mechanical properties of Equal Channel Angular Extrusion Nb and Ultra-fine grain Cu-Ta:
Performed mechanical tests to reveal the properties of ECAE Nb and UFG Cu-Ta. Discovered significantly improvement of the mechanical properties through ECAE and mixing immiscible metallic elements. Used TEM to analyze the microstructure of Cu-Ta alloy, the addition of Ta significantly improved the thermal stability of the alloy.
Characterized the nano-hardness of High Pressure Torsion Ta:
Conducted nanoindentation experiments to obtain nano-hardness profile along the radius of the HPT Ta sample; statistically analyzed the grain size distribution with OriginLab and TEM. Established the relationship between the plastic work, grain size and hardness values.
Analyzed the microstructure of MMC/MMNC Mg:
Used TEM to analyze the micro-structure of the Mg samples, statistically analyzed the SiC nano-particle size and distribution inside the samples using ImageJ and OriginLab, and investigated the mechanical reinforcement effect of the nano-SiC particles.
