The Debye–Scherrer pattern of the alloy Ni 80 Zr 20 clearly shows the presence of a nickel solid‐solution phase along with a new intermetallic phase Ni 23 Zr 6 , which seems to be isostructural with the Co 23 Zr 6 phase. The thermal expansion coefficient of the Ni 23 Zr 6 phase has been investigated in the temperature range 1003–1493 K. Linear variation of lattice parameter with temperature has been observed. The thermal expansion coefficient remains almost constant throughout this temperature interval.
