| Abstract: | The enthalpies of formation of liquid Ni-Zr alloys have been measured through the composition range 0 < Xzr < 0.4, where Xzr is the mole fraction of Zr. Four independent runs were made at temperatures ranging from 1740 to 1743 K and one at 1838 K.
The compositional dependence of the enthalpies of formation could be fitted quite well with polynomial representations according
to the subregular as well as to the sub-subregular solution approximations. The influence of chemical short-range order was
found to differ from the earlier Ni-Ti results. |
