摘要: AbstractLiquid tin solution calorimetry has been used to measure the enthalpies of formation iron-cobalt alloys covering composition range 7.6 91.0 at.-% iron. Measurements at two temperatures (475 and 775 K) allowed extrapolation 923 K which temperature free-energy measurements are available for combination with determine entropies formation. The low values these lead speculation about possible sources substantial negative contributions point necessity low-temperature heat capacity resolve problem. compositional dependence enthalpy results indicates a maximum non-stoichiometric 53 at-% This, deductions concerning value order/disorder transformation, in keeping previous work on system.
