摘要
In the present study, amorphous Ti50Cu35-xNi 15Snx (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 50Cu35-xNi15Snx 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-xNi15Snx (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.
