Abstract
Abstract The crystallization behaviour of amorphous Ni67Zr33 alloy has been studied by transmission electron microscopy (TEM). Two metastable phases, T0 and T1, have been found at 500°C in a needle-like morphology. The T1 phase has a body-centred orthorhombic unit cell (a = b = 0·90, c = 3·14nm) and the Iba2 space group. As the temperature increases, the metastable phase T1 changes gradually through various transition states (T2) with an A-centred orthorhombic lattice of the stable Ni10Zr7 phase. The diffraction streaks in T2 may be due to the presence of stacking faults on the (001) plane in Ni10Zr7 with a translation vector of ½(a + b). The final products of crystallization are the equiaxial stable phases Ni10Zr7 and Ni21Zr8.
