The mechanism and kinetics of oxidation of Inconel 617 and 625 alloys in air atmosphere were investigated. Materials were examined by the thermogravimetric method. The X-ray diffraction spectrometer (XRD) was used to observation change in chemical composition the oxide scales of Inconel alloys specimens. Oxidation kinetics was determined from weight-change measurements. The surface and microstructure of the sample were observed in an optical microscope (OM) and a scanning electron microscope (SEM). The results showed that the oxide scales of the alloys were compact and continuous. The layer were contained as the outer of Cr2O3, and the internal of NiCr2O4 spinel, NiO and other oxides. Oxides’ scales with good adherence were formed on the surface of alloys. The kinetics and thermodynamic parameters of oxides formation were calculated and discussed for both alloys.

The paper brings results of examinations of main thermo-physical properties of selected Inconel alloys, i.e. their heat diffusivity, thermal conductivity and heat capacity, measured in wide temperature range of 20–900°C. Themathematical relationships of the above properties vs. temperature were obtained for the IN 100 and IN 713C alloys. These data can be used when modelling the IN alloys solidification processes aimed at obtaining required structure and properties as well as when designing optimal work temperature parameters.

Praca dotyczy badań głównych właściwości termofizycznych wybranych stopów typu Inconel, to jest dyfuzji ciepła, przewodności cieplnej i ciepła właściwego, mierzonych w szerokim zakresie temperatury 20–900°C. Matematyczne zależności ww. właściwości w funkcji temperatury dotyczą stopów IN 100 oraz IN 713C. Uzyskane w badaniach dane mogą być wykorzystane podczas numerycznego modelowania krzepnięcia i projektowania stopów typu IN o pożądanej strukturze i właściwościach a także projektowania optymalnych temperaturowych parametrów pracy.
