Název v původním jazyce

Phase transformations temperatures of real steel grade

Popis výsledku v původním jazyce

The paper deals with the study of phase transformations temperatures of real peritectic micro alloyed steel grade. Phase transformations temperatures were obtained using Differential Thermal Analysis (DTA) and Setaram Setsys 18TM laboratory system. There are presented results from the low temperature region (below 1000 °C) and high temperature region (above 1000 °C). Extrapolation of obtained phase transformation temperatures to “zero” mass and “zero” heating rate is performed. The following temperatures of phase transformation were determined: eutectoid transformation (740 C), end of alpha-gamma transformation (845 °C), start of gamma-delta transformation (1472 °C), peritectic transformation (1486 °C) and liquidus temperature (1511 °C).The obtained phase transformations temperatures are discussed. Phase transformations temperatures are calculated using thermodynamic and kinetic software ThermoCalc and IDS also. Experimentally obtained data of phase transformations temperatures are compared with calculated data and discussed. Experimentally obtained data are essential for thermodynamic calculations and they are used also as input data for numerical mathematical and physical models.
