Термодинамика взаимодействия празеодима с эвтектическим расплавом галлий-алюминий

Abstract

Thermodynamics of interaction of Pr with Ga-Al eutectic alloy was studied employing the EMF method. Thorough mathematical processing of obtained EMF temperature dependences measured between metal Pr and two-phase Pr-Ga-Al alloys allows us to conclude thattwo peritectic reactions of intermetallic compounds (IMC) have had happened. Temperatures of both reactions decently correspond to phase transitions of well-known IMCs of Pr with Ga. It indicates that prereferentially interacts with gallium.
