Crystallisation of amorphous Al-Y-Ni-(Cu) alloys

Abstract:

The nanocrystallisation behaviour and subsequent intermetallics formation of an amorphous Al 88 -Y 4 -Ni 8 alloy has been studied. A 1 at.% of Al or Ni was also substituted by Cu and its effect studied. Differential scanning calorimetry has been used to measure the thermal stability of these amorphous alloys. Transmission electron microscopy showed the smaller size of the nanocrystals obtained during primary crystallisation when Cu is added. Using three-dimensional atom probe, it has been che...
