  • Patent number: 11162165
    Abstract: Disclosed herein is a nickel-based heat-resistant material with improved cyclic oxidation properties. The nickel-based heat-resistant material containing gadolinium (Gd) according to the present invention is capable of suppressing the de-lamination of an oxide layer and increasing stability of the oxide layer, thereby forming an overall thin and uniform oxide layer, and has an advantage in that the formation of a nitride may be suppressed since nitrogen is prevented from penetrating through the oxide layer. In addition, due to the slow oxidation rate, there is an advantage in that an Al depletion layer (a ?? denuded zone) by the formation of an oxide layer may be formed to be very thin compared to that of a specimen having no gadolinium added.
