We performed calorimetric measurements of the enthalpy of formation of amorphous alloys created using vapor quenching in a highly immiscible system, Ag-Ni. The low-enthalpy states observed, as compared with extrapolated liquids and crystalline solid solutions, are in agreement with the findings from molecular dynamics (MD) simulations. The MD results support the proposition that the enthalpy reduction is associated with the ultra-fine-scale phase separation in the liquid/amorphous state. © 2001 American Institute of Physics.
