⁶³Cu NMR Study of Cu₈₃-Zn₁₇ Mixed Powders During Mechanical Alloying

The variations of the ⁶³Cu NMR, spectra of Cu₈₃-Zn₁₇ powder mixtures with time of ball milling arc shown and analyzed. With increasing the ball-milling time, the α phase is developed as terminal phase over 5h. accompanying the emergence aid following disappearance of siiiall aniount β phase. The microstructural changes after aging at room temperature are also detected. Some valuable conclusions related to the alloying reaction on an atomic scale have been drawn.
