The distortion of the crystal lattices in a metal under stress has provided a valuable means of studying these stresses. The best method of non-destructive study is through x-ray diffraction techniques. The stress-strain relationships have been thoroughly studied by many investigators, each using his own modifications of the basic principles involved. This thesis presents another method of studying the stress-strain relationships in metals by means of x-ray diffraction. The investigation was carried out with non-focused x-ray diffraction cameras. The stress distortions in metals are easily found on x-ray patterns, but the accurate measurement of the small changes is rather difficult. It was hoped that some inherent non-focused features of the camera would magnify or offer some definite photographic indication of the stresses. All of this work was carried out using a series of aluminum alloys. These alloys were photographed while under various stresses by means of x-rays. Special calibrated jigs were devised to facilitate the photographing of the specimens.
