Description
  • Thermophysical properties are the critical input parameters in mathematical models of solidification and casting of metallic materials. Existing property data are sometimes only available for selected pure elements and a few simple alloys and compounds and often the techniques available for their measurement are subject to considerable uncertainty. For highly complex materials a complete thermodynamic description of the system involves a huge amount of work, and the predicted values differ from those measured. In this work the technique of Differential Thermal Analysis (DTA) was selected for the study of nickel based superalloy IN 738LC. Particular attention was given to the phase transformation temperatures determination in high temperature region and to the effect of varying heating/cooling rate on these temperatures.

  • Termofyzikální vlastnosti jsou kritickými vstupními parametry matematických modelů procesů tuhnutí a odlévání. Data, která jsou v dnešní době dostupná, jsou dostupná především u vybraných čistých kovů, některých jednoduchých slitin a sloučenin a postupy jednotlivých měření podléhají často značným nejasnostem a nepřesnostem. Kompletní termodynamický popis systému složitých komplexních materiálů vyžaduje velké množství práce a předpokládané hodnoty se od těch měřených liší. V předkládané práci byla pro studium niklové superslitin IN 738LC vybrána metoda Diferenční termické Analýzy (DTA). Zvláštní pozornost byla zaměřena na zjištění teplot fázových transformací ve vysokoteplotní oblasti a na stanovení vlivu rychlosti ohřevu/ochlazování na tyto teploty. (cs)
