Abstract
The enthalpies of formation were measured in the intermetallic compounds ZrNi5, Zr2Ni7, Zr7Ni10, ZrNi, and Zr2Ni, and the amorphous Zr1−xNix alloys with x=0.25, 0.35, and 0.65 by means of a solution calorimeter based on liquid aluminium. For the amorphous system Zr1−xNix, the concentration dependence of the crystallization enthalpy was studied by means of differential scanning calorimetry on 12 different compositions. The concentration dependence of the formation enthalpy of the crystalline materials was analyzed in terms of Miedema’s model. The enthalpy effects observed in some of the amorphous alloys point to the occurrence of compositional short-range ordering.This publication has 10 references indexed in Scilit:
