Abstract
To obtain the X-ray diffraction pattern of a flat specimen such as is met with in metallurgical practice, the specimen may be mounted in a circular camera and inclined at a small angle to the beam. This is illustrated in Fig. 1. With the usual diaphragm, we have observed that diffraction lines making a small angle with the surface of the specimen are particularly sharp, but become broader as the angle between the diffracted beams and the surface of the specimen increases.
