The shot-peened surface of AA 5083 under the influence of elevated temperature

The paper deals with the elevated temperature influence on shot-peened surface of 5083 aluminium alloy. Shot-peening introduces the compressive stress in the surface layer of the metal, changing the resulting tensile residual stresses. After the specimen had been exposed to the elevated temperature, the yield and the tensile strength were tested. The test results indicate that elevated temperature treatment is significant on the shot-peened of AA 5083, although the positive effect of peening is not entirely gone.
