Abstract
Isothermal and non-isothermal differential scanning calorimetry experiments were carried out to study rapidly solidified Al90Fe5Ce5 alloy. Microstruct ural analysis suggests that icosahedral nanoparticles are homogeneously dis tributed in the matrix of annealed amorphous Al90Fe5Ce5 alloy. The presence and homogeneous distribution of icosahedral structure units and icosahedra l short-range domains appear to be critical for the formation and stability of the amorphous phase.
