Abstract

In order to minimize the crystal phase in Al-Cu-Ti amorphous powder, Al₆₅Cu_35-xTi_x amorphous powders were optimized via ball milling through adjusting the amount of Cu and Ti elements and the ball milling time. The results show that increasing the mole fraction of Ti can decrease the amount of AlCu₂Ti, Cu₉Al₄, and Al₂Cu intermetallics formed during the process of ball milling; and prolonging the ball milling time can reduce the element crystalline phase to almost none. The optimal composition is determined to be Al₆₅Cu_16.5Ti_18.5. TiH₂ forms in all selected Al₆₅Cu_35-xTi_x amorphous powders during the process of optimization. H atom is decomposed from toluene and reacts with Ti during ball milling, leading to the formation of TiH₂. The volume fraction of TiH₂ in Al₆₅Cu_16.5Ti_18.5 amorphous powder is measured to be 4.30%.
