ABSTRACT

Ni–Cr–Mo alloys undergo a disorder to order transformation via a short-range order. Enhanced defect concentration is known to accelerate ordering kinetics. However, a sluggish ordering kinetics has been observed in splat-quenched Ni2(Cr0.5,Mo0.5) alloy that contained higher quenched-in defect. This curious observation of abnormal kinetics has been explained on the basis of smaller driving force for ordering due to the suppression of short-range order in splat-quenched samples.
