| Research Abstract |
3D visualization demonstrates that martensite packet is zigzagged and has a specific habit plane, and block is zigzagged. All packets observed reach to a prior austenite boundary.
Preliminarily, quantification of 3D image was attempted using a parameter such as genus, Euler characteristic, Gauss curvature and mean curvature, which suggested that those topological or differential geometrical parameters seems to be useful to characterize microstructures in metals.
