Abstract

"Pole figure scans of strip rolled from copper, nickel, titanium, and tungsten metal powders were made on samples taken across the width of the strip, and with various amounts of surface material removed, to determine if any preferred orientation existed. No preferred orientation was found in any of the samples examined.

The method used was a modification of the Schultz technique, using the Norelco Pole Figure Fixture, whose geometry and operation is described, in conjunction with the Norelco diffractometer.

Defocusing resulting during the run of a pole figure is discussed and a method for reducing this defocusing is described.

The rolling of metal powders is briefly discussed and the method used to roll the strip used in the investigation is described.

It was found that it was desirable to prepare the pole figure specimen so that its surface is as flat and smooth as possible, preferably by a polish-etch procedure, in order to prevent spurious intensity recordings.

Examination of the microstructures of the various sheets indicated that the larger the particle size, the greater the deformation of the particles in the green strip"--Abstract, pages ii-iii.
