Study of thermo-physical properties of selected nickel-based superalloys with use of DTA method

Popis výsledku v původním jazyce

The presented paper deals with study of thermo-physical properties of cast complex alloyed nickel based superalloys IN713LC; IN738LC and IN792-5A. In this work the technique of Differential Thermal Analysis was selected for acquisition and comparison ofthe phase transformation temperatures. Moreover, the transformation temperatures for zero heating/cooling rate were calculated. Based on a comparison of these temperatures it is possible to make the following conclusions: (i) The alloy IN792-5A has the highest temperature of solubility of the strengthening phase 7' (1235 degrees C); (ii) the highest liquidus temperature (heating) obtained by extrapolation was found in the alloy IN713LC (1349 degrees C), the lowest solidus temperature (heating) was foundfor the alloy IN738LC (1212 degrees C); (iii) At cooling an undercooling occurred in all alloys. In general it may be stated that the biggest under-cooling (TS, 47 degrees C) was recorded in the alloy IN792 5A; (iv) The width of. the int
