Crystallization Behavior of Al-Y-Ni-Co Metallic Glass

Abstract:

As an important lightweight and high-strength structural material, aluminum alloy is the optimum material for airplane and aircraft. Amorphous Al-based alloys are attractive materials for structural applications because of their high strength of about 1000MPa. Crystallization behavior of amorphous Al-based alloys is critical to the synthesis of high-strength nanocrystalline aluminum alloys in bulk form. The crystallization behavior of an Al₈₅Y₈Ni₅Co₂ metallic glass produced by rapid solidification of the melt was studied in this paper. Microstructure transformation during crystallization was identified by X-ray diffraction. It is found that the initial crystallization of the amorphous alloy occurs through the precipitation of α-Al particles, followed by precipitation of hcp-Al₃Y and an unidentified phase.
