Alloying of immiscible phases in wire-drawn Cu-Ag filamentary composites

摘要

The microstructure of Cu-6.1at.%Ag thin wire cold drawn to a true strain of η = 9.6 has been investigated by a three-dimensional atom probe. Substantial mixing progressed and the Ag concentration of Ag filament decreased to only 22 at.%atη = 9.6. This is believed to be a part of the reasons for the low electrical conductivity of the severely cold drawn composite wire.
