AbstracLThe amorphous Cu@Ti4+.2r, (I = 0, 10, 20 and 30) alloys were sucaessfully synthesized k y mechanical alloying of pure elemental pavders of Cu, ' l i and Zr using a planetary high.energy ball mill. The u m t u r e and thermal behaviour of there alloys were analysed by x-ray diffraction and differential scanning calorimetry. The resulls indicate that the replacement of li by Z r increases the chemiml driving force of the amorphization leaction and the intemclion of dissimilar atoms of the I3-li-B ternary system. Thus, the glassforming tendency, the amorphization rate and the Yabilily are all improved. In addition. the stability of Cu-Ti-= amorphous @em is related lo the nyslalliation sequence and the first nyslalliiation phase.
