Abstract
THE distribution of plastic deformation in a cold-stretched mild steel bar has been studied by X-ray diffraction methods. Using the back-reflexion technique with cobalt radiation, two spotty rings were obtained by reflexion of the K α doublet from the (310) plane of iron. Plastic deformation in the specimen was indicated by a blurring of the spots of the diffraction patternas the individual crystals, which gave the reflexions, became distorted. An X-ray beam of about 1 mm. diameter was used to explore the distribution of the deformation.
