Abstract
Early studies in the 17:2 phases based on Pr, Nd and Sm for relatively low absorption temperature (400 degrees C) showed that the diffusion pattern is different from the shell-core model. Instead, the diffusion occurs at phase and grain boundaries. The precipitation of the satura ted phase occurs along these boundaries. In this work we show, using d ifferent characterization methods, that the same behavior is observed for the 17:2 phases based on Sm, Gd, Ho, Tb.
