Smith thermal analysis of selected Pr–Mg alloys

Abstract

The Smith thermal analysis has been used in the experimental investigation of several Pr–Mg alloys to achieve a better definition of some of the phase equilibria characteristic of the Pr–Mg system. This technique has several advantages with respect to conventional thermal analysis methods, even though it is more time consuming and it can be applied only to relatively narrow ranges of temperature in any one experiment. Solvus lines in the Pr-rich region and temperatures of the invariant reactions of the Mg-rich region of the Pr–Mg system were re-determined.
