Smith thermal analysis of selected Pr-Mg alloys

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 thou gh it is more time consuming and it can be applied only to relatively narro w 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. (C) 2001 Elsevier Science B.V. All ri ghts reserved.
