Abstract
Abstract Diffusion couples and equilibrated alloys have been investigated in order to contribute to the knowledge of Ti –Zn phase diagram. Differential scanning calorimetry, X-ray methods and scanning electron microprobe analyses are applied. Diffusion couples studies show that TiZn3 layers grow directly from the Ti–Zn liquid phase at 700 °C. Eight thermal peaks were observed in the interval 400–620 °C. Six of these peaks belong to stable three-phase equilibria and two are probably associated with metastable equilibria. Anew version of the Ti–Zn phase diagram, in the zinc-rich region, has been constructed.
