Characterization of the evaluation of the solid solubility of Si in sintered Fe–Si alloys using DSC technique

Differential scanning calorimeter (DSC) is used to quantify the solid solubility of Si in sintered Fe–Si alloys. The calorimetry tests are run on Fe–Si alloys by arc melting and sintering. The relationship between the Curie temperature and the solid solubility of Si in Fe–Si alloys was determined using DSC. The solid solubility of Si in sintered Fe–Si alloys evaluated according to the relationship between magnetic transition and compositions can be compared with the results from a related quantitative electron probe microanalysis (EPMA).
