Outline of Final Research Achievements

Material properties strongly depend on a morphology of its microstructure. In this study, automatic and quantitative evaluation method using mathematical morphology was developed.
Combination of mathematical morphology methods such as an WaterShed method could improve an evaluation accuracy and efficiency of primary phase size distribution of Al-Si alloy. And automatic calculation method of major and minor axis of particles enabled automatic calculation of aspect ratio of bended thin particles in meta-cera material.
