Abstract

The thin-layer lathe-sectioning technique has been used to measure the solute diffusivities of zinc in b.c.c. and double-h.c.p. praseodymium. The diffusivities in the b.c.c. phase can be expressed by D = 6·3 × 10–1 exp (–27 000/RT) cm2/sec, and in the double-h.c.p. phase by D=1·8 × 10–1 exp (–24 800/RT) cm2/sec. The diffusion behaviour of zinc is similar to that of previously studied noble metal solutes. These solutes are believed to diffuse by means of the combined substitutional–interstitial diffusion mechanism. It is therefore suggested that zinc is partly dissolved as interstitials in the praseodymium matrix.
