| Abstract: | The thermodynamic conditions under which the amorphous solidcan be formed by means of a solid--state reaction technique, i.e. amorphizationby mechanical alloying(AMA), were discussed. Miedema model was applied tothe calcu1ation of the glass forming range(GFR) of Co--Ti binary system insolid--state reaction. Some expressions were also used to take the differencein Gibbs free energy of amorphous phase and that of crystalline phase, regard-ing the system as a single component. The results are in conformity to thoseby Gallego and H.Kimura especially that of late by authors. |
