Non-isothermal crystallization kinetics of FeZrB amorphous alloy

► The crystallization kinetics of FeZrB amorphous alloy is investigated in continuous heating process. ► The first step crystallization is easier to be occurred than the second step. ► The crystallization of the first and second steps is dominated by low and three dimensional nucleation and growth, respectively. ► The nucleation rates of the first and second steps increase firstly and then reduce.
