Strain distributions in the deformed layer of Al alloys strained by abrasion with emery papers were studied by X-ray diffraction. The strain in the tensile and tear tested specimens was also studied. The equivalent plastic strain is the strongest on the specimen surface and weakens with the depth from the specimen surface. The specimen surfaces abraded with emery papers of #120, #700 and #1000 have equivalent plastic strains 4.5, 6.4 and 1.8% respectively bearing an indistinct relation to the roughness of emery papers. The deformation layer thins down with the roughness of the papers. When machined by a shaper, the equivalent plastic strain amounts to 58%. When two regions differently deformed coexist, the equivalent plastic strain is greatly determined by a smaller strain. Measured and calculated strains in the necked region in the tensile tested bars have a good correlation up to the reduction of area about 40%. Tear test specimens have large values of equivalent plastic strain over a wide range from the tip of the crack.
