Abstract
The crystallization characteristics of an amorphous NiZr2 alloy have been studied by transmission electron microscopy. Striations in NiZr2 crystallites were found to be narrow twin bands, sometimes only a few layers thick, with 〈110〉 as the twin axes and a rotation of ±120°. High-resolution lattice images prove the composition plane to be the {110} planes perpendicular to the 〈110〉 twin axes. This twin relationship can be accounted for by the existence of a hexagonal cluster of Ni and Zr atoms parallel to {110} within the body-centred tetragonal unit cell of NiZr2.This publication has 9 references indexed in Scilit:
