ABSTRACT:
NiCrAl alloys are improved by the addition of zirconium. These alloys are in the .beta. or .gamma./.gamma.'+.beta. region of the ternary system.
Zirconium is added in a very low amount between 0.06 and 0.20 weight percent. There is a narrow optimum zirconium level at the low value of 0.13 weight percent.
Maximum resistance to cyclic oxidation is achieved when the zirconium addition is at the optimum value.
