- Abstract
The exact eutectoid and peritectoid temperatures in near equiatomic Zr-Pd compositions have been determined by using the diffusion couple method and microstructure analysis. The crystal structure of Zr13Pd12 compound were estimated to be orthorhombic with <italic>a</italic> = 1.78 nm, <italic>b</italic> = 0.80 nm and <italic>c</italic> = 1.00 nm from the electron diffraction experiments. The Zr13Pd12 compound is formed at 1100 ± 2 K with a peritectoid reaction between Zr2Pd and ZrPd compounds. The ZrPd compound transforms to Zr13Pd12 and Zr9Pd11 compounds by a eutectoid reaction at 1028 ± 4 K. Based on these results, the phase diagram of near equiatomic Zr-Pd binary system is reconstructed.
