Outline of Final Research Achievements

In this study, it was clarified that difficulty in an X-ray stress measurement is caused by not fixed a diffraction centre. As the countermeasure, we proposed a double exposure method (DEM). In the DEM, the diffraction points were measured at two different points and the line of the diffracted X-ray beam is determined by the two points. The stress of the coarse-grained materials can be measured using the DEM. For example, the residual stress distribution of the indented specimen was measured using the DEM. Our residual stress map corresponded to the simulated results.

Academic Significance and Societal Importance of the Research Achievements

これまで,X線応力測定は,粗大粒(微小領域),集合組織,溶接部に適用困難とされていた.本研究はその原因を明らかにしたことの意義は大きい.また,その原因を克服するために,回折中心を仮定するこれまでの測角方法を止揚して,独創的な測角法を提案した.その手法は,回折ビームと入射X線の直線関係から角度を決定し,かつ回折位置も解析できる優れた手法である.この回折測定方法は新しい方法であり,学術的にも工業製品の開発にも大いに役立ち注目に値する.
