Calculated phase diagram for the system Cu-Ti. The Cu-Ti system is characterised by fairly extensive primary solid solution phases and 5 intermetallic phases with compositions lying between approximately 20 and 66.67 at.% Ti [86Mas, 94Oka]. The phases with compositions denoted as CuTi and Cu4Ti display narrow ranges of stoichiometry.

The phase relationships of the Cu-Ti-Er ternary phase diagram at 773 K (500 °C) were investigated mainly by means of X-ray powder diffraction (XRD), scanning electron microscopy (SEM) with...
Formation of typical Cu–Ti intermetallic phases via a liquid …
2019年10月1日 · Typical Cu–Ti intermetallic phases, namely, CuTi 2, CuTi and Cu 4 Ti 3, are formed via a fast liquid-solid reaction approach. Large grain sizes of such phases enable the evaluation of pertinent properties such as microhardness and fracture toughness. CuTi 2 is brittle in nature and exhibits an extremely symmetrical cracking pattern.
Formation mechanism and microstructure evolution of Cu/Ti …
2023年7月1日 · Cu/Ti joints with excellent mechanical properties were fabricated by diffusion welding. Four intermetallic compounds CuTi 2, CuTi, Cu 4 Ti 3 and Cu 4 Ti were formed on the interface. The residual stress mainly concentrated in CuTi 2 and CuTi phases. The fracture of the Cu/Ti joint mainly occurred in the CuTi and Cu 4 Ti 3 phase.
The Cu-and Ti-ions in the low-symmetry ordered phase of CuTi 2 …
There are three inequivalent Ti ions (Ti (1), Ti (2), Ti (3)). The Ti–Ti bond lengths are substantially different (they are marked by different colors). The theory of structural phase transition in...
Table 1 shows Cu-Ti crystal structure data from [Mas-salski2] with additional information on CuTi3 from [2002Can]. [1951Kar] reported earlier that CuTi3 had an AuCu-type tetragonal structure with a P4/mmm space group.
(Q S, Se), Cu0.5Co0.5Cr2Se4, Cu(CrxTi1 x)2S4, Cu2CoTixSn3 xS8 (or 1⁄4 CuCo0.5Tix/2Sn(3 x)/2S4) and CuTi2S4, have many interesting mag-netic, thermoelectric, electrochemical and optical properties [1–9]. The spinel structure of CuM2Q4 (Q S, Se) presents the M cations in 1⁄4 octahedral sites (16d) and Cu cations at its tetrahedral sites (8a).
