Analysis methods
Area method
The micrograph shows a heat-treatable steel using the example of C45 (normalized, Nital etching). The aim was to detect the red colored part of ferrite.
Line method
The micrograph shows a heat-treatable steel using the example of C45 (normalized, Nital etching). The red marked line segment indicates the percentage microstructure of ferrite (bright phases).
Point method
The micrograph shows a heat-treatable steel using the example of C45 (normalized, Nital etching). The percentage ferrite is visualized by red crosses.
