Notes:
in the present study, amorphous ti50cu35-xni15snx (x=0~7) alloy powders weresynthesized by mechanical alloying technique. the amorphization behavior of ti50cu28ni15sn7 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 Ti50Cu35-xNi15Snx amorphous powders was investigated by differential scanning calorimeter. The amorphous Ti50Cu35Ni15 powders (i.e., x=0) exhibit no glass transition behavior. However, the amorphous Ti50Cu35-xNi15Snx (x=3~7) powders werefound to exhibit a supercooled liquid region before crystallization. AmorphousTi50Cu28Ni15Sn7 alloy powders exhibits a wide supercooled liquid region of 61 K
