  • METALLIC MATERIAL AS A SOLID SOLUTION HAVING A BODY-CENTERED CUBIC (BCC) STRUCTURE, AN ORIENTATION OF CRYSTAL AXIS <001> OF WHICH IS CONTROLLED, AND METHOD OF MANUFACTURING THE SAME
    Publication number: 20120312432
    Abstract: An orientation of crystal axis <001> of the metallic material as a solid solution having a structure of body-centered cubic (BCC) is arranged along a work surface of the metallic material by hot rolling process in a temperature range of structuring the metallic material to be BCC single phase solid solution. For example, Fe-Si alloy as the metallic material is heated in the temperature range for BCC single phase solid solution, and processed so as to arrange the orientation of crystal axis <001> along the work surface by pressing the BCC single phase solid solution in a strain rate to maintain work condition for controlling motion of dislocation by atmosphere of solute atom generated in BCC single solid solution and migrating grain boundary by strain energy stored in a crystal grain as driving force.
