With the development of modern society,
higher performance materials are increasingly needed in many industries, and as a consequence, worldwide efforts have been concentrated to develop materials with higher specific strength and ductility, fracture and fatigue resistance as well as higher formability. Such materials will comprise essential structural parts of next generation transportation vehicles, i.e., high speed trains, high performance automobiles, supersonic aircrafts and space shuttles.
In order to meet this industrial needs,
our laboratory was established in 1987 focusing the research activities on the topics of Fatigue and Plasticity of various metallic alloys. Particularly, it is a great challenge to enlighten the high temperature deformation mechanisms of various metallic alloys, and to clarify the microstructural influence on the fatigue resistance and formability of materials.
In the area of fatigue,
the microstructural and environmental factors influencing fatigue properties (high cycle fatigue, low cycle fatigue and fatigue crack propagation) are investigated by using Ti, Al and ferrous alloys. Recently, life prediction models for HCF and LCF have been extensively studied and confirmed by experimental verification.
In the area of plasticity, research efforts have been devoted to understand the mechanism of high temperature deformation and to develop the intelligent forging processes of Ti, Al, and Fe alloys via computer simulation.
In the area of hydrogen embrittlement (HE),
it is aimed to develop high strength steels with enhanced HE resistance and excellent fatigue properties.

Our laboratory pursues,
Our purpose is to clarify the role of various microstructural factors such as, grain boundary, twin boundary, dislocations, precipitates and so on.
I sincerely hope that this site is of some help for your understanding of our laboratory. If you have any comments and suggestions, please write to us. We will do our best to incorporate your ideas and opinions.
Thank you for your interest and support.
