Ln. Larikov et al., MECHANICAL ALLOYING DURING INTERACTION BETWEEN ZINC POWDER AND COPPER, Powder metallurgy and metal ceramics, 36(9-10), 1997, pp. 455-458
We have investigated mechanical alloying by interaction of zinc powder
with copper in a rotating drum. Grinding down of the powder particles
and penetration of the chippings into the surface layers of the coppe
r occurs in the early stages. The most disperse zinc chippings are dis
solved during simultaneous plastic deformation of the copper and the z
inc. Then a thin layer of the intermetallic compound gamma-Cu5Zn8 is f
ormed by reactive interdiffusion. We discuss the mechanisms for mechan
ical alloying.
