Devitrification of amorphous alloy Al$_{87}$Ni$_6$Nd$_7$ under heat treatment

The structure and thermal effects of crystallization of amorphous alloy Al$_{87}$Ni$_6$Nd$_7$ have been investigated by X-ray diffraction and differential scanning calorimetry. It is shown that crystallization proceeds in three stages. The activation energy of three stages of crystallization of amorphous alloy Al$_{87}$Ni$_6$Nd$_7$ has been calculated. It is found that after the third stage of crystallization the structure of the alloy is fully crystalline and consists of crystals of Al, Al$_{11}$Nd$_3$ and a previously unknown phase.
