Abstract

The x-ray line width from specimens of cold worked $\ensuremath{\alpha}$-brass and tungsten has been measured as a function of Bragg angle and of x-ray wave-length. The results are in agreement with a microstress theory of broadening. In $\ensuremath{\alpha}$-brass the line width is found to depend on crystallographic direction in a systematic manner while with tungsten it does not. Both observations are explained on the basis of the elastic properties of the materials.
