Abstract
In this paper, functional surface development by controlling crystalline structure on surfaces of materials is suggested. In order to reveal the mechanism of crystalline structure change by Nano Plastic Forming method, plastic deformation characteristics of single crystal pure iron are examined experimentally by means of shearing tests. Stress-strain curves are measured and Critical Resolved Shear Stresses of activating slip systems are calculated based on crystal plasticity theory. Besides shearing tested specimens are annealed and crystalline structure are analyzed by EBSD for study of effects of microscopic plastic deformation and annealing on recrystallization.
