Study of the dissolution kinetics of the θ phase in AlCu alloys using thermoelectric power measurements

Abstract A comparative study of the dissolution kinetics of θ precipitates in an AlCu alloy was made using classical methods (hardness, scanning electron microscopy and differential scanning calorimetry) and thermoelectric power (TEP) measurements. It is shown that TEP measurements are the most suitable method. The advantages and limitations of this method are given.
