Abstract
Abstract A series of Zn–Ce–Ti alloys was designed to investigate the 600 and 450 °C isothermal sections of the Zn–Ce–Ti system based on examination by Scanning Electron Microscope (SEM) equipped with Energy Dispersive X-ray Spectrometer (EDS) and X-ray Powder Diffraction (XRD). No ternary compounds were found in the system. Twelve 3-phase regions were identified at 600 °C and thirteen 3-phase regions at 450 °C. Ce does not dissolve in any of Ti–Zn binary compounds and the solubility of Ti in Ce–Zn binary compounds was less than 1.0 at.%. TiZn3 phase can equilibrate with CeZn11, Ce2Zn17, and Ce3Zn22, while TiZn can achieve equilibrium with Ce3Zn22, CeZn5, Ce13Zn58, and Ce3Zn11. Differential thermal analysis results together with SEM-EDS analysis proved that the decomposition temperatures of TiZn16 and Ti3Zn22 were 461.8 and 613.1 °C, respectively.
