Abstract
Coextrusion and corolling are the major processes
to produce bimetallic rods, tubes and
wires, the objective being to perform clad metals,
bimetallic joints or seals. The aim of the present
work is to produce bimetallic rods showing an ultra
fine grained microstructure with enhanced
properties. Bimetallic Cu-Al rods were deformed by
equal channel angular pressing (ECAP) in
order to study their microstructure. ECAP is an int
eresting process for producing bulk materials
with refined microstructure and, consequently, chan
ges in physical, chemical and mechanical
properties can be observed. Higher shear strength a
nd dimensional stability are among the
advantages of this process. A comparative experimen
tal study of pure commercial copper with
cylindrical inner aluminium rods of different diame
ters processed by one-pass equal channel
angular pressing has been carried out. The ECAP die
used in this research was a 90º 2-channels
intersecting angle. Electron backscattered (EBSD) a
nd X-ray diffraction techniques were used for
microstructure characterization (deformation, grain
fragmentation and microstrain evaluation) at the
interfaces and away from them. It was found that th
e microstructure in the ECAP deformed Cu-Al
bimetallic rods was influenced by the dimensions of
the aluminium inner rod. In fact, the
microstructure appeared to be much more elongated a
nd refined in the samples containing smaller
diameter aluminium rods.
