Abstract:
|
In this work we study the structural evolution of Al and Fe based metallic glass
compositions. The samples were obtained as ribbons by melt-spinning, their glass stability and
crystallization were analyzed by calorimetry and dilatometry, structural changes were followed
by in-situ synchrotron X-ray diffraction during annealing throughout glass transition and
crystallization. The synchrotron results are compared with calorimetric and dilatometric
measurements and the structural changes occurred during annealing are determined and
described for each alloy. |
