Summary
-
1.
The effect of dispersed oxides of aluminum, magnesium, and chromium on the deformation resistance of a nickel alloy (Monel) differs from their effect on pure nickel. The addition of the oxides increases the deformation resistance of Monel only at fairly high temperatures.
-
2.
The absence of any effect of the oxides on the resistance of Monel to compression at room temperature and at moderately high test temperatures is attributed to the predominant influence on the deformation resistance of Monel at these temperatures of hardening caused by alloying and by the formation of solid solutions of variable composition.
-
3.
The addition of dispersed oxides to Monel displaces the recrystallization range in the high-temperature direction, increases the temperature of maximum softening, and reduces the extent of the softening. When recrystallization is complete, alloys of Monel containing oxides have a finer grain size and greater hardness than Monel without oxide additions.
