precipitates forms on Ni-10Al, while Ni-5Cr-10Al develops a protective layer. So the addition of Cr promotes the formation of alumina scale. The possible mechanism of Cr on the oxidation of Ni-Al alloy is discussed. Key words: Ni-Cr-Al alloy; Ni-10Al alloy; oxidation; third-element effect 1 Introduction Binary and ternary Ni-based alloys are often used as model systems to study the processes occurring......
) into Ni-7Al and Ni-10Al inhibits the internal oxidation of aluminum and considerably reduces the critical content of Al needed to form exclusive alumina scales with respect to binary Ni-Al alloy, providing... and Ni-10Al alloys at 1 100 ℃ was studied. 2 Experimental The nominal compositions of the four alloys were Ni-7Al, Ni-10Cr-7Al, Ni-10Al, and Ni-10Cr-10Al. The corresponding actual composition of each alloy......
