Spark plasma sintering aids in characteristic eutectic structure free microstructural evolution in hypereutectic Al-Si. The mechanism of suppression of characteristic eutectic was elucidated through current-voltage evolution during sintering, electron backscatter diffraction phase mapping and high-angle annular dark field imaging. The electric current activated eutectic melting at the Al-Si interface followed by rapid heat transfer lead to a microstructural evolution under far from equilibrium condition and free from conventional eutectic structure. © 2020 Elsevier B.V.
