Abstract

In the present study, amorphous Ti₅₀Cu_35-xNi ₁₅Sn_x (x=0-7) alloy powders were synthesized by mechanical alloying technique, the amorphization behavior of ti₅₀cu ₂₈sn₇ alloy powders was examined in details by scanning electron microscopy, differential scanning calorimeter, x-ray diffraction, and synchrotron x-ray absorption spectroscopy. the results show that fully amorphous powders formed after 7 hours of milling. The thermal stability of the Ti ₅₀Cu_35-xNi₁₅Sn_x amorphous powders was investigated by differential scanning calorimeter. The amorphous Ti ₅₀Cu₃₅Ni₁₅ powders (i.e., x=0) exhibit no glass transition behavior. However, the amorphous Ti₅₀Cu _35-xNi₁₅Sn_x (x=3-7) powders were found to exhibit a supercooled liquid region before crystallization. Amorphous Ti ₅₀Cu₂₈Ni₁₅Sn₇ alloy powders exhibits a wide supercooled liquid region of 61 K.
