“…In the past ten years, more and more attention has been paid to Co-Zr and Co-Ti alloys. In the Co-Zr system, the presence of six compounds (i.e., Co 11 Zr 2 , Co 23 Zr 6 , Co 2 Zr, CoZr, CoZr 2 , CoZr 3 ) was confirmed and their phase diagrams and thermodynamic evaluation were reported [18,19]. Likewise, there are five kinds of compound (TiCo 3 , h-TiCo 2 , c-TiCo 2 , TiCo and Ti 2 Co) in Co-Ti system.…”

Co2Zr and Co2Ti are both cubic crystals with a Cu2Mg-type structure. The elastic, thermodynamic and electronic properties of the intermetallic compounds Co2Zr and Co2Ti are investigated by using ab initio plane-wave pseudopotential density functional theory (PWPDFT) and generalized gradient approximation (GGA) under high temperature and pressure. The partially calculated results are consistent with the available experimental data. The elastic properties of Co2Zr and Co2Ti under high pressure were first studied by first principles calculations. The results indicate that the elastic constants, elastic modulus and Poisson’s ratio are functions of pressure, indicating that the effect of pressure on the ductility and anisotropy is significant. The thermodynamic properties are also calculated by the quasi-harmonic Debye model. In the range of 0~100 GPa pressure and 0~1500 K temperature, the Debye temperature Θ, the heat capacity CV and the thermal expansion α vary with pressure and temperature. Co2Ti has a higher Debye temperature than Co2Zr under the same pressure. Decreasing temperature and increasing pressure have the same effects on CV and α. The electron density difference and density of states of Co2Zr and Co2Ti are finally investigated. The results show that both Co2Zr and Co2Ti are typically metal crystals but Co2Zr has greater covalence than Co2Ti.

“…So far, a serial of ternary systems related to the nine-element system such as Fe-Ni-Ti [17], Fe-Ni-Zr [18], Cu-Fe-Ti [19], Cu-Ti-Zr [20], Co-Cu-Ti [21], Ni-Ti-Co [22], Ni-Cr-Ti [23], Co-Ti-Zr [24], Co-Cr-Zr [25], Cu-Cr-Zr [26] and Ti-Cr-Mn [27] have been well carried out. Some other ternary systems related to the nine-element system need to be further researched.…”
