Contribution to the zinc-rich side of the Ti–Zn system

The 450 °C Isothermal Section of the Zn-Fe-Ti System

“…[14] This compound has been included in the phase diagram proposed recently by Vassilev. [22] The presence of this phase at 450°C substantiates the early finding that the peritectic temperature of its formation is 460°C, [10,11] higher than the 445°C indicated by Massalski. [46] The T phase is more resistant to etching than the TiZn 16 .phase.…”

“…The exact composition of this phase is Ti 2.841 Zn 22.159 , which corresponds to the TiZn 8 phase. Most likely, these two phases are the same, although Vassilev [22] suggested recently the existence of both TiZn 7 and TiZn 8 . The minor The microstructure of Alloy 17 is shown in Fig.…”

“…In the initial trial, the Ti powder was found to react with the quartz tube, fused SiO 2 in nature, at high temperatures to form Ti oxides [22,47,48] due to the extremely negative standard Gibbs energies of formation of the oxides. As a result, the mixtures had to be contained in corundum crucibles that were then sealed in evacuated quartz capsules.…”

“…[9][10][11][12][13][14][15][16][17][18][19][20] However, the nature of these compounds is still a subject of discussion. Recently, Vassilev et al [21,22] proposed a new version of the Zn-rich side of the phase diagram. These researchers believe that the intermediate phases in the system are not necessarily all line compounds and could exist in the vicinity of their respective stoichiometry, probably in metastable states.…”

Reaction kinetics and phase diagram studies in the Ti–Zn system

“…As consequence, at cooling two other invariants are crossed (Fig. 8A)-one is the eutectic line (T ≈ 419 • C), while the other (T ≈ 460 • C) could be attributed [26] to the peritectic reaction: Liq + TiZn 8 ↔ TiZn 10 .…”
