The amorphization transformation of al-y-ni system by mechanical alloying was inves- tigated in both thermodynamic and kinetic *** amorphous powder of al-rich composition al_(80)y_(15)ni_5 was formed after 70 h *** process of the amorphiza- tion was monitored by X-ray *** dependence of the amorphization on the milling intensity was also *** results show that over milling with extra-high intensity has an unfavourable effect on amorphization of the system.
