Abstract

Activation Energy Crystallization Kinetics DSC Measurements
By liquid quenching technique, for instance, alloys of early transition metals (Zr, Nb, Ti, Ta) and late transition metals (Fe, Co, Ni, Cu, Pd) can be quenched rapidly from the melt to form glasses. These systems form glasses of near deep eutectic composition. Various amorphous alloys can be formed from Ti-Ni. In this study, the synthesis of rapidly solidified Ti-27%Ni alloy was conducted by melt spinning technique. Differential scanning calorimetry (DSC) measurements were made using a Perkin-Elmer DSC-2C under flowing argon, in the interval 323-873 K. Crystallization temperatures T x of 761.26 K, 773.42 K, and 782.72 K, were obtained at heating rates 10 K/min, 25 K/min, 40 K/min respectively. The XRD patterns were obtained using a Rigaku D/max-IIB, X-ray diffractometer with Cu K α radiation.
