Presence of multivalency/non-stoichiometry to accommodate a different-sized cation and maintaining electroneutrality were identified as the critical criteria for single-phase formation in multicomponent/high entropy systems.

ABSTRACTThe effect of a thin Ta layer at the Ti/Si interface on the kinetic of the C49-C54 transition will be shown in detail. The transformation kinetic has been monitored by in situ sheet resistance measurements that, coupled to structural characterisation, allowed to evidence the presence of an intermediate phase before the C54 formation. The temperature of the C54 phase formation decreases with a Ta concentration of 4.5·1015 cm−2 and μ-Raman images of partially transformed samples indicates that the density of C54 grains in presence of Ta is about one order of magnitude higher with respect to pure Ti/Si samples.

Lateral growth of intermediate phase during reactive diffusion was analyzed. Proposed model is based on the assumption that the main driving force of the lateral growth process is the chemical one (proportional to composition gradient along the interface). Asymmetric case of phase formation taking into account the curvature of all three interfaces at the triple joint is considered.
