Academic Degree
Dr. Engineering
Field of Specialization
Ductile Fracture Mechanics, Thermoelectric Material,Computational material engineering
Outline Activities
1)It is necessary to improve the ductile fracture property witch is a dominant factor of press formability in the case of applying high strength steels to actual parts. Our research team showed recently that voids nucleation sites of pure iron made by elecrlolytic process were cross points of double slip. The nitride-quenchinng treatment is studied in our laboratory to improve the surface hardness of steel. 2)New thermo-electrical material with chemical composition gradient are studying to apply in the condition at the constant temperature. This thesis was adopted by NEDO project in 2015-2016 year.
