Abstract : The role of the rate of severe plastic deformation (SPD) during equal-channel angular pressing (ECAP) on
microstructure and strength are studied. ECAP was performed at room temperature to refine grain size of pure Al of
rectangular cross-section. The examination of the microstructure has been undertaken using ascanning electron microscope.
The mechanical properties of the ECAP processed material are investigated. The tests show that the hardness increase
isaffected by the amount of the strain rate on pure Al. Also, it was observed that a lower strain rate produces a homogeneous
microstructure with equiaxed grains more quickly than with higher strain rate and the yield strength increases up to three times.
