摘要: The material flow and crystallographic orientation in aluminum alloy sheets joined by friction stir welding (FSW) were investigated electron back scattered diffraction (EBSD). microstructure microtexture of the near zone was found to be influenced rotational behavior tool pin. It that, during FSW, forward movement pin resulted loose contact between receding at advancing side. This inside plates also observed an X-ray micrograph inlaying a gold marker into plates. As speed increases given rotation speed, region widens. is very close simple shear texture on basis frame normal tangent directions, amount incompletely rotated due could estimated from tilt angle pole figure around key hole.
