<div>Ti nanoparticles were deposited on a glass substrate by a gas aggregation source and coated with a thin layer of Niunder different deposition conditions. The resulting composite consists either of a mixture of TiO2-covered Ti nanoparticles or core-shell Ti-Ni nanoparticles embedded in the Ni matrix. The thermal stability of the composite was studied during in-situ heating in the transmission electron microscope. Corresponding changes in the morphology of nanoparticles and the phase composition of the material were analyzed by energy-dispersive X-ray analysis and scanning (transmission) electron microscopy. The influence of the heating rate during the quasi-isochronal heating regime was tested. The coagulation of Ni in the Ti-Ni core-shell system was confirmed by molecular dynamics simulation.</div>
