Experimental work on nickel indicates the existence of a stress below which dynamic recrystallization does not occur. The limiting condition for dynamic recrystallization is that the recrystallized grain size must exceed the minimum size for the stability of a nucleus. Applying this condition to olivine indicates that the maximum possible dynamically recrystallized grain size probably exceeds the grain sizes commonly observed in mantle xenoliths.
