For the first time, a combination of scanning transmission electron microscopy and electron back-scattering diffraction is used to elucidate the early stages of particle stimulated recrystallisation at Nb carbides in Ni-30wt.%Fe alloy subjected to high temperature plane strain compression. While particles with sizes even below 1 μm were found to induce dynamic or metadynamic recrystallisation, only a small fraction of coarse particles served as nucleation sites. - Highlights: • The early stages of particle stimulated recrystallisation at Nb carbides are elucidated • A combination of transmission electron microscopy and electron back scattering diffraction used • Particles below 1 μm size could induce dynamic or metadynamic recrystallization.
