Abstract

Abstract Structural stability of glassy Al 85Ni 10La 5 as-atomized powder was investigated after ball-milling using differential scanning calorimetry, X-ray diffractometry, and transmission electron microscopy. Fcc-Al nanocrystals were found after ball-milling. The crystallization behavior upon thermal treatment depends on the deformation level. This is ascribed to a shift in the composition of the residual amorphous phase towards higher contents of Ni and La during ball-milling.
