Comparison 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 super-alloys IN713LC, IN738LC and IN792-5A. In this work the technique of Differential Thermal Analysis was selected for acquisition and comparison ofthe phase transformation temperatures. The samples taken from super-alloys in as received state were analysed at heating and cooling rates of 1, 5, 10, and 20 K/min. Moreover, the transformation temperatures for zero heating/cooling rate were calculated. 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 super-alloys, during controlled heating/cooling of the initial material (as received state) during DTA analyses, all the samples of super-alloys were subjected to a phase analysis using scanning electron microscopy.
