Outline of Final Research Achievements

The morphology of the second phase in the metal and metal matrix composites has a great influence on the mechanical properties of the material. We proposed the three-dimensional and the two-dimensional local number (LN3D and LN2D) and the image mean free path (IMFP) as a method for quantitatively evaluating the microstructure, and furthermore, we developed software component groups (including machine learning techniques) to measure these values automatically. In addition, the statistical meaning of the measured value was clarified by computer simulation, and the relationship between the mechanical properties of the material and its measured value was investigated.
