Anotace:
The contribution deals with experimental monitoring of
segregation processes and evaluation of mechanical
properties of austenitic chrome-nickel steel CF3M. Segregation
was determined on the basis of measurements
of the chemical composition in the experimental casting
and calculation on the basis of numerical simulations in the
MAGMASoft program. The experimental casting was of
a cube shape with edges of length 500 mm. In the framework
of the evaluation the segregation of chosen elements
from the point of view of macrosegregation and microsegregation
was studied. Steel properties were evaluated in
chosen places of the casting during the tensile test.
