Abstract: The crystallization processes of 2826A (Ni₃₆Fe₃₂Cr₁₄P₁₂B₆) metallic glass were investigated using differential scanning calorimetry (DSC) at various heating rates. The thermograms at all scanning rates show two exothermic events. Different methods of kinetic analysis were employed at non-isothermal condition to derive important kinetic parameters namely activation energy of crystallization (E), frequency factor (A) and Avrami exponent (n) for the two exothermic peaks. The obtained values of E for peaks 1 and 2 are 298 and 457 (kJ/mol), respectively. The obtained Avrami exponent values 2.2(peak1) and 1.6(peak2) indicate one-dimensional and surface crystallization, respectively.
