Comparison between symmetric and asymmetric hot rolling techniques performed on duplex stainless steel 2205

In this work the alterations of mechanical properties of two 6xxx Aluminum alloys during different states of a production process are investigated. The mechanical properties are determined by means of the tensile test. Tensile tests are performed shortly after four steps in the production process: the shipment of the two alloys, a certain period of storage, uniaxial pre-stretching, and heat treatment that corresponds to the temperature profile during e-coating. Results are displayed as a function of orientation with reference to rolling direction, as a function of the level of uniaxial pre-stretching and as function of the temperature profile.
