The study shows that the resultin. n.cleation.of partial dislocation. on.the free surface an. their glide occurs through local fcc→bcc→hcp tran.formation. via con.isten. atomic displacemen.s. We propose an.atomic model for the gen.ration.of dislocation. an. twin. based on.local reversible fcc→bcc→fcc tran.formation., with the reverse on. proceedin. through an.altern.tive system.
