Abstract
Microstructure evolution of hot extruded AZ31 magnesium alloy
during twist channel angular pressing was investigated. The
grains were refined significantly after one to four passes at
200°C. Microstructure evolution after TCAP processing was
investigated using optical microscopy, transmission electron
microscopy and electron backscatter diffraction. The results
show effect of TCAP process on the achieving the UFG structure
with average grain size below 1 μm.
