To understand the nanocrystallization process of amorphous Nd3.6Pr5.4Fe83Co3B5, activation volumes for the growth of nanocrystals in the alloy have been determined directly by measuring the rate constants varying with pressure at different temperatures. At T = 773 K, the activation volume for the growth of α-(Fe,Co) phase is determined to be (0.50 ± 0.02)Ω, where Ω is the mean atomic volume of the alloy, and it increases slightly to (0.59 ± 0.03)Ω at T = 823 K. The activation volume for the growth of (Nd,Pr)2Fe14B phase at T = 823 K is determined to be (0.52 ± 0.02)Ω. The effect of temperature on the activation volume for nanocrystal growth is discussed.
