DSC - Opis:
- The paper describes the primary crystallization of metallic Fe95Si5 glass which was studied by differential scanning calorimetry (DSC) with non-isothermal methods. The activation energy of crystal transformation was calculated with the equations proposed by Kissinger, Mahadevan and a modified version of the equation developed by Augis and Bennett. Activation energy was determined at Ea = 242.0 - 254.2 kJ / mol, subject to the applied method. The Avrami exponent of crystallization in the amorphous phase n was determined in the range of n = 2.40 - 2.52, depending on the method of calculating the transformation of activation energy.
