| Summary: | The study deals with precise determination of phase transformation
temperatures of steel. A series of experimental measurements were carried
out by Differential Thermal Analysis (DTA) and Direct Thermal Analysis (TA)
to obtain temperatures very close to the equilibrium temperatures. There are
presented results from the high temperatures region, above 1000°C, with
focus on the solidus temperatures (TS), peritectic transition (TP) and
liquidus (TL) of multicomponent steels. The data obtained were verified by
statistical evaluation and compared with computational thermodynamic and
empirical calculations. The calculations were performed using 15 empirical
equations obtained by literature research (10 for TL and 5 for TS), as well
as by software InterDendritic Solidification (IDS) and Thermo-Calc (2015b,
TCFE8; TC). It was verified that both thermo-analytical methods used are set
correctly; the results are reproducible, comparable and close to equilibrium
state. |
