X–ray diffraction studies of Al–Ni–Zr ternary alloy

Abstract

Alloys of ternary Al-Zr-Ni ternary system of with stoichiometric ratio of Zr, Ni and Al 1:2:5 has been studied by X-ray diffraction method at room temperature and in the temperature region close to melting point. It is shown that within wide temperature region exists the tendency to chemical ordering. The results of investigation allowed refining the crystalline structure of ternary intermetallics to calculate an interatomic distances in $ZrNi_{2-x}Al_{5-x}$ phase.
