A Study of Preferred Orientation of Thin - Walled Chemically vapor Deposited Tungsten Tubes

Abstract
Procedures were developed in the X-ray method for routine measurement of preferred orientation for chemically vapor deposited tungsten tubes. The interpretation of the experiment data is based on the inverse pole figure technique. Preferred orientation measurements indicated that the grains in the circumferential, longitudinal, outside, and inside sections contain mainly{100} planes and that the fiber axis of the tube is <100>. This method is very rapid and is generally best suited to the problems involved with fabricated shapes, such as tubes.
