| Description
| - 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 of the 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 found for 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 interval of the heat treatment window was the biggest in alloy IN713LC (44 degrees C); (v) The alloy IN738LC is characterised by the widest interval of melting (124 degrees C) and solidification (134 degrees C), while the alloy IN792 5A has the narrowest interval of melting (82 degrees C) and at the same time almost the same interval of solidification as the alloy IN738LC (129 degrees C); (vi) The obtained phase transformation temperatures were compared with the values of phase transformations temperatures calculated on the basis of established relationships. In order to obtain more precise description of the behaviour of Ni-based superalloys, during controlled heating/cooling of the initial material (as received state) during DTA analyses, all the samples of superalloys were subjected to a phase analysis using scanning electron microscopy.
