We have utilized differential scanning calorimetry to monitor the solid-state reaction of crystalline metals to form an amorphous alloy in multilayered thin-film diffusion couples of elemental Ni and Zr. The heat of formation of amorphous Ni/sub 68/Zr/sub 32/ alloy from the elemental metals is measured directly and found to be 35 +- 5 kJ/mole. The kinetics of these reactions have been examined. The activation energy for interdiffusion in the amorphous phase is determined to be E = 1.05 +- 0.05 eV.
