Abstract

The crystallization behavior and phase formation in Zr₅₅Ni ₁₀Al_7.5Cu_7.5Ti₁₀Ta₁₀ metallic glass have been studied by x-ray diffraction, transmission electron microscopy and differential scanning calorimetry. Mutual addition of Ti and Ta is found to benefit the formation of the icosahedral phase in the glassy phase on heating without energy barrier for nucleation. The value of the activation energy for nucleation and growth estimated by Kissinger analysis also supports this result.
