On the Orientation of Cell Block Boundaries in the Grains of a Rolled F.C.C. Polycrystal

Abstract:

Grains in f.c.c. polycrystals that accommodate imposed deformation purely byslip processes develop a multi-scale dislocation substructure that evolves with deformation.When the polycrystal is subjected to rolling deformation or to channel-die compression, oneof the elements of this substructure, called cell block boundaries, are widely reported to alignparallel to the transverse direction and close to the macroscopic plane of maximum shear. Thisobservation is explained based on standard rate-independent crystal plasticity augmented bythree hypotheses.
