Professor Wujun Yin's research lab specializes in the design, processing, and mechanical behavior of advanced metallic materials, with a focus on magnesium-based alloys and high-strength steels. The lab investigates microstructure–property relationships, particularly how phase morphology, texture, and deformation mechanisms influence strength and ductility. Using advanced characterization techniques such as atom probe tomography and high-resolution digital image correlation, the lab explores nanoscale strain localization and phase partitioning in complex multi-phase systems. Current research directions include optimizing extrusion processing in Mg-Zn-Y alloys and understanding the micromechanics of quenching and tempering (Q&T) and quenching and partitioning (Q&P) steels.

In long period stacking ordered (LPSO) phase containing Mg-Zn-Y alloys, high elastic modulus and deformation kinks of LPSO phase considerably enhance the tensile yield strength, with slight detriment of or benefit to the ductility depending on its volume fraction. In present work, uniaxial tensile tests and fracture toughness tests are carried out using Mg99.2Zn0.2Y0.6, Mg97Zn1Y2, Mg89Zn4Y7 and Mg85Zn6Y9 (at%) materials with different extrusion ratios. Extrusion processing enhances both strength
Exploring the micromechanical behavior of lath-martensitic quenching and tempering (Q&T), as well as quenching and partitioning (Q&P) steels presents a significant challenge due to their complex multi-phase constituents and hierarchical structures. This study conducts a comprehensive comparative analysis using medium-carbon Q&T and Q&P steels with identical chemical compositions. Atom probe tomography (APT) was used to investigate the distribution of chemical elements, while high-resolution digi
