Thesis abstract:

I am working on project of Improving Mechanical Properties of High-Entropy Alloy (HEA) via introducing Gradient Structures. This project aims is to improve mechanical properties via structural manipulation and to correlate the deformation mechanisms with properties. The reliability and functionality of HEA depend strongly on their mechanical properties which could be enhanced by changing microstructure from homogeneous to gradient distribution of microstructure. We used rotationally accelerated shoot peening technique to create gradient structure on HEA. After that did Vickers hardness and tensile test to reveal mechanical properties. Various electron microscope such as TEM, SEM and FIB used to understand deformation mechanisms.
