摘要: Abstract The enthalpies of formation solid nickel—zinc alloys have been measured at 355 K using an isoperibol calorimeter and the technique tin-solution calorimetry, values obtained for nickel-rich α-solid solutions β 1 , γ, γ δ intermediate phases. Exothermic observed throughout these compared with results in previous free energy studies those suggested by empirical model Miedema. existing data re-assessed 900 combined present calorimetric to derive entropies formation. possible contributions phases are discussed their Debye temperatures estimated.
