The action of an electric pulse of high current density on a powder compact can induce multiple physical phenomena, including inter-particle sintering and melting of the material. The present work was aimed at studying the morphological and structural features of metallic glass – crystalline metal compacts consolidated by applying a single electric pulse. A 40 vol% Fe66Cr10Nb5B19 metallic glass – Cu mixture was consolidated under pressure by a pulse of electric current generated by a capacitor bank. The input energy was varied to determine the formation conditions of a robust composite compact. The possibility of consolidating a mixture of a Fe-based metallic glass and copper by a single pulse of electric current while avoiding crystallization of the glassy component was demonstrated.
