| Abstract: | Non-isothermal crystallization process in amorphous alloys Ni35Ti65 and Ni40Ti60 before and after high-energy heavy ion irradiation with 150 MeV Ni+11 ions have been investgated using differential scanning calorimetry (DSC). The alloys have been irradiated with fluences varying between 1 ×1011 and 1 × 1013 ions/ cm-2. DSC traces have been analyzed in terms of activation energy for crystallization, Avrami exponent dimensionality of growth by using four different models viz. Kissinger equation [J Res NBS, 57 (1956) 2 17], Ozawa equation [Bull Chem Soc Jpn , 35 (1956) 881], Matusita equation [J Mater Sci, 19 (1986) 291] and Gao and Wang equation [J Non-Cryst Solids, 87 (1980) 129]. No effect of heavy ion irradiation of above mentioned energy, on the crystallization kinetics has been found. |
