Abstract

The effect of Al addition to Ni₆₀Nb₄₀ on the thermal property and crystallization behavior of amorphous phase was investigated by using thermal analyses, X-ray diffractometry (XRD) and transmission electron microscopy. As melt-spun amorphous (Ni₆₀Nb₄₀)_100-xAl_x (x=0, 3, 5, 10at.%) alloys crystallizes through two exothermic reactions, corresponding to precipitation of nanoscaled crystalline phase followed by formation of the rhombohedral Ni₆Nb₇ phase and orthorhombic Ni₃Nb phase. With increasing the Al content, the first weak exothermic peak shifted to lower temperature region and the second exothermic peak shifted to higher temperature region. The addition of Al promotes the formation of Ni₃Al phase in the first exothermic reaction. The amorphous (Ni₆₀Nb₄₀)_100-xAl_x alloys show low value of heat of crystallization, which may be related with structural similarity between amorphous structure and final crystallization products. Fully amorphous rod with diameter of 1mm could be fabricated by injection casting (Ni₆₀Nb₄₀)_100-xAl_x (x=0, 3, 5at.%) alloys. Further addition of Al deteriorates the glass forming ability.
