Abstract
AT the suggestion of Prof. J. Reekie of the University of Toronto, I have carried out a few experiments on the cold working of aluminium at room and liquid air temperatures. These show that although the metal is spontaneously self-recovering during cold working at room temperatures, it shows lattice distortion effects if the plastic deformation is carried out at the temperature of liquid air and the specimen is maintained at that temperature. The aluminium used was ‘H.S.' brand, supplied by Messrs. Johnson Matthey and Sons, Ltd. The X-ray back-reflexion method was chosen for investigation of lattice distortion.
