In-situ orientation rotation behavior study during tensile deformation of aluminum single crystal and polycrystal

Abstract

Orientation rotation behaviors taking place in aluminum single crystal and polycrystal were studied during uniaxial tensile deformation at room temperature. Specimens were elongated in an in-situ deformation stage equipped on a high resolution electron backscattered diffraction (HR-EBSD) system. A series of crystallographic evolution and deformation behavior of concerned areas in the specimens during deformation was directly analyzed using HR-EBSD.
