during welding. Grade 91 steel transformed into thousands of fine polygonal crystals to lower its high energy absorbed from the adjacent hot liquid. Welding/joining of metallic materials has been a critical technique during structural construction. A sound weld/joint ensures integrity of the entire
structure components. The quality of the interface determines the strength of this weld. Interface structure control is a hot research topic in welding engineering. My name is Yiyu Wang, a 3rd-year PhD student from Department of Chemical and Materials Engineering. My research focuses on microstructure
characterization and properties evaluation of steels and steel joints by using advanced microscopy techniques. I am addicted to adventuring the mysteries of steels under microscopes. // Program of Study: PhD // Faculty/Department: Chemical and Materials Engineering // Place of creation: CME Building, University
