Recrystallization and Grain Growth in NiAl

Metallurgical Transactions A Aims and scope Submit manuscript

Abstract

Experiments have established that upon annealing, warm-worked NiAl recrystallizes and undergoes subsequent grain growth in a manner typical of metals and alloys. The recrystallization and grain growth kinetics, respectively, can be described by the expressionsX v = 1 - exp(-Bt k) and −d =Ct n where Xv is the fraction recrystallized,t is time, −d is the average grain size, andB, k, C, andn are parameters whose magnitudes depend upon temperature.
