摘要	The thermodynamic process of an amorphous-to-nanocrystalline transformation in a Ni-P alloy system was investigated calorimetrically. It was found that its thermodynamic properties (DELTAH, DELTAS, and DELTAG) are much different from those of the usual amorphous-to-crystal transformation, which may be attributed to the formation of interfaces in the products. The entropy change was positive rather than negative (as in usual crystallization), and its value increases with an increase of temperature. Structural investigations and the comparison of the properties of the two different solid states, as well as the transformation thermodynamics results show that the interfaces in the nanocrystalline material are more disordered and more defective, and consequently exhibit a larger entropy than the amorphous phase.
