The influence of heat treatment and deformation on structural changes of Al-based amorphous alloys in the amorphous state and at early stages of crystallization has been studied using the methods of X-ray diffraction, differential scanning calorimetry and transmission electron microscopy. It is shown that isothermal annealing and multiple cold rolling bring about formation of an inhomogeneous amorphous...
The effect of high stress and high temperature on the structure of binary Al90Y10 amorphous alloy has been investigated. Deformation of the alloy was carried out by high pressure torsion at room temperature; heating was produced up to 220°C.It was revealed that both treatments leaded to the primary crystallization of the alloy. Produced Al nanocrystals were randomly distributed over the amorphous...
