- 論文の詳細を見る
Neutron and X-ray scattering studies were carried out in the temperature regionabove the "two-tetragonal-mixed" phase discussed in part I of this series of paper.Quasi-elastic scattering were observed to increase as the temperature was decreasedtoward the transition point from fcc to the intermediate phase. The results were infer-preied as due to random distribution of micro-regions of the low temperature struc-lure (embryonic fluctuations) whose density increasing with decreasing temperature.Together with the results discussed in part I, the process of the first order phase transi-lion in Fe-Pd was inferred by dividing the temperature region into the four regimes asfollows; cubic phase (regime (I))=random distribution of tetragonal ernbryos(regime (II)) -+ two-tetragonal-mixed phase (regime (III))-+tetragonaI phase withvariants separated by sharp domain boundaries (regime (IVY).
