Outline of Final Research Achievements |
First, we have investigated mechanisms of the new fatigue performance in the steel and the Al alloy that had been found by the present researchers, in order to develop the new ways to design and create high performance materials. Based on the proposed mechanisms, we have developed new steels and Al alloys that exhibit higher resistance to fatigue damage and hydrogen embrittlement along with the new academic research field of fatigue crack propagation. Key was utilization of the dynamic change of material property at a fatigue crack tip. We believe that our research achievements contribute to the field of material science and engineering from the industrial and academic viewpoints.
