The structure and thermal effects of crystallization of amorphous alloy Al87Ni6Nd7 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 Al87Ni6Nd7 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, Al11Nd3 and a previously unknown phase. Keywords: amorphous alloys, nanocrystalline alloys, thermal effects, activation energy, X-ray diffraction.
