Heat Resistance and Heat Capacity of the Selected Nickel Superalloys

Abstract:

The paper presents results of tests into heat resistance and specific heat capacity of nickel-based superalloys: Rene 80, Mar-M-200+Hf i Mar-M-247+Hf. Heat resistance tests were carried out with the use of a cyclic method. Each cycle involved a 23-hour period of heating at 1100oC, followed by 1-hour air cooling. The DSC method was applied to determine specific heat. Scale microstructure was examined with the use of an electrone microscope. The tested alloys have been proven to enjoy relatively good resistance to corrosion. The Mar-M-200+Hf alloy enjoys the highest specific heat capacity, while the lowest value of specific heat has been recorded for the Mar-M-247+Hf alloy.
