Аннотация: Age-hardened Cu-rich copper-titanium alloys are used for the fabrication of high strength springs, electrical contacts, diaphragms, and for developing corrosion and wear-resistant materials. To improve the performance of these materials, Cu-Ti is often alloyed with other elements such as Co. In order to better understand the role of alloying elements basic information is essential including phase diagrams of related systems. Phase equilibria in Co-Cu-Ti were studied experimentally in [1968Pfe, 1993Ali, 2006Liu, 2006Wan, 2006Xu, 2007Wan]. [1968Pfe] found that for Ti33Co8Cu57 the MoSi2-type phase predominated. Later [2006Liu, 2006Wan, 2007Wan] accepted this phase as a ternary compound. [1993Ali] constructed a quasibinary TiCo-TiCu section of the eutectic type. Isothermal sections for all concentrations were constructed at 650°C [2007Wan], 700°C [2006Liu], 750°C [2006Wan] and 850°C [2006Liu, 2006Xu]. There are also some reviews by [1979Abr, 2003Gup, 2010Yan]. [1979Abr, 2003Gup] made an analysis of data obtained by [1968Pfe] only. [2003Gup] noted that the phase analysis, given by [1968Pfe], might be incomplete. Based on three binary systems and on the measured isothermal sections of the ternary system, a thermodynamic description of the Co-Cu-Ti ternary system was carried out by [2010Yan]. Enthalpies of formation of TiCo and TiCo2 during heating of the quenched alloys were determined by DSC experiments [2008Don, 2010Don1, 2010Don2]. Details of all investigations of the ternary Co-Cu-Ti phase relations, structures and thermodynamics, including experimental details are listed in Table 1. Document ID: 10.15712.1.5
