Formation of Amorphous Powders of Alloys of the Cu-Ti System with Mechanical Activation of Powder Mixtures

摘要

The active mechanical treatment (AMT) of powdermixtures of the Cu-Ti system in a high-powder mill and in amedium-powder vibrating ball mill in argon allows one tosynthesise the phases and to obtain the powders in an amorphous(by X-ray measurements) state. AMT of mixture proceeds via thefollowing stages: grinding of precursor powders, formation of alayered structure, interdiffusion (mass transfer), and attainmentof on amorphous state.
