RESEARCH AREA

  • Physical metallurgy, structure/property relationships on ultra-high strength steel
  • Hydrogen embrittlement in ultra-high strength steel
  • Zn-assisted liquid metal embrittlement on advanced high strength steel
  • Surface science and the coating technology for advanced high strength steel

TECHNICAL FOCUS

My research focused on the physical metallurgy of coated, advanced high to ultra-high strength steels. Previously, I was involved in the research projects on the surface coating quality-related issues of various high-alloyed advanced high strength steels. The projects involved the in-depth study of the oxidation process in high-alloyed steels and its interaction with Zn- and Al-based metal coating system. More recently, I investigated the hydrogen embrittlement fracture in aluminized ultra-high strength press hardened steel. The primary goal of the research was development of hydrogen-resistant ultra-high strength press hardened steel. I am currently involved in the research project on the liquid metal embrittlement fracture behavior on Zn-coated advanced high and ultra-high strength steels during high-temperature deformation.
