Martensitic transformation behavior and phase equilibrium in Zr-Pd alloys have been investigated. Near equiatomic Zr-Pd alloys quenched from above 1073 K undergo a martensitic transformation at around 830 K. However, the ZrPd compound transforms to Zr13Pd12 and Zr9Pd11 compounds by a eutectoid reaction at about 1040 K. It is also found that the Zr13Pd12 compound forms by a peritectoid reaction between Zr2Pd and ZrPd at about 1100 K. A modified equilibrium phase diagram between Zr2Pd and Zr3Pd4 in the Zr-Pd binary system is proposed.
