Abstract The crystallization of amorphous Ni_(83)Cr_7Fe_3Si_4B_3 alloy was investigated under dynamic heating and isothermal annealing conditions. An identical crystallization and unaltered phases are revealed under both treatments. However, the initial crystallization is mainly due to the nucleation of crystals under dynamic heating, while the crystal growth plays a major role under isothermal annealing. It has also been measured that the microhardness approached its highest value just before the specimen being totally crystallized.
