The size-dependent phase diagram for Ni-based systems by combination of CALPHAD and ab initio method
Original language description
The method for the CALPHAD modelling of size-dependent phases diagram for simple systems was published by Tanaka et al. and Park et al. [1.2]. The new approach for the modelling of size-dependent phase diagrams was developed by the authors [3]. The combination of CALPHAD approach with the ab initio calculations of surface stresses for stoichiometric and nonstoichiometric intermetallic phases allows to calculate the phase diagrams in dependence of the nanoparticles size also for complex systems with intermetallic phases. The binary Ni-based systems were modelled in the scope of this study, both theoretically and experimentally with the aim to describe the influence of the phase boundaries on the size of the particle. The synthetized nanoparticles were studied by DLS, SAXS, TEM, and DSC methods. Obtained temperatures of invariant reactions obtained by DSC are compared to calculated results and reasonable agreement was obtained. The binary system were used to model the behaviour of ternary Ni-Sb-Sn system and compared with the results published by Mishra et al. [4]. Again the agreement was found to be reasonable.
