Abstract
This paper will review work done in our laboratory on the formation, thermodynamics and crystallization of aluminum based metallic glasses. The results demonstrate that the metallic glasses are truly amorphous and not microcrystalline and that they are unusual in their formation because the alloys contain up to 90 at.% aluminum, there is no deep eutectic present in the phase diagram and the reduced glass temperatures are low (0.44) relative to the ease of glass form ability in this system. Tensile strengths that exceed 1200 MPa are obtained for several of the compositions and reveal increased strength values after partial crystallization. Various methods to form nanocrystals of aluminum in an amorphous matrix are discussed and include mechanical and thermal processing.
