Method for monitoring the crystallographic texture of metallic tubes by use of X-ray diffraction

摘要

The crystallographic texture of metallic tubular articles is characterized by an X-ray diffraction technique where X-rays are directed onto the surface of the tubular article and diffracted X-rays detected by use of a position-sensitive detector. By effecting relative movement of the tubular article and the X-ray source in both a rotational direction about the axis of the tube and in an axial direction, and measuring intensities from multiple Bragg peaks of the diffracted X-rays from a plurality of locations on the tube, the crystallographic texture of the tube is characterized.
