Deformation and Recrystallization of Tensile-deformed or Rolled Fe-3%Si Alloy Single Crystals

Fe-3%Si alloy single crystal samples with various tensile directions were deformed to strains of 0.25 to 0.65 and subsequently annealed. Necking occurred and work-hardening was very small in all tensile-deformed samples. After annealing, no recrystallized grain was formed. Fe-3%Si alloy single cryst...

Description
Summary:Fe-3%Si alloy single crystal samples with various tensile directions were deformed to strains of 0.25 to 0.65 and subsequently annealed. Necking occurred and work-hardening was very small in all tensile-deformed samples. After annealing, no recrystallized grain was formed. Fe-3%Si alloy single crystal sample of {111}‹112› orientation was lightly rolled to 25% and subsequently annealed. Many recrystallized grains were formed in the rolled sample. The orientation of recrystallized grains formed at the rolled surface was totally different from the orientation of those formed in the interior of the sample. These results are discussed based on the tendency for cross-slip and the dislocation network model for nucleus of recrystallized grain.
