• Duplex stainless steel
• Asymmetric rolling
• Anisotropy
• Texture

Laboratory asymmetric rolling trials have been developed at different temperatures on EN 1.4462 duplex steel grades imposing different reduction ratios and different asymmetric rolling ratio. The samples have been also subjected to a subsequent solution quenching. The asymmetric rolling operations have been performed in order to impose significant shear strains in the bulk regions of the rolled sheets, because during the traditional rolling the shear strains tend to become very weak and theoretically null at the middle point of the thickness. The mechanical properties, the pointed out anisotropy, the micro-structural features and the texture characteristics have been discussed as a function of the imposed operative parameters: thermal level, reduction ratios, rolling ratios and possible application of solution quenching after the rolling.
