Results and discussion
The results of observations, measurements, and calculations of
the samples under investigation are presented in Figs. 1e4 and in
the Tables 1e3. Fig. 1 presents photographs of the surfaces taken
with the optical microscope in the polarized light and with the scanning microscope. It is possible to see the grains of the previously
existing austenite as different shades outlined on the surface
of both samples.
