Figure 2

The examples of complex microstructure patterns observed in optical microscopy images of two A-steels with same composition, but obtained with different cooling rates of 1 °C/s (a) and 3 °C/s (b) from 1400 °C and having different mechanical properties. The manual identification of different microstructures is shown with arrows.
