Abstract
The texture development in a hot rolled Cu-14.2wt.%Zn-5.6wt.%Al in the surface and centre of the sheet was studied. The observed texture in the centre of the sheet can be understood in terms of the {001}(011) and {211}(011) hot rolling texture in the austenite phase and the reported crystallographic orientation relationships between monoclinic martensite and b.c.c. austenit. In the surface of the sheet the texture was developed with the influence of shear deformation. Therefore in the martensitic phase only the orientation components were observed which were originated from the {001}(011) of the b.c.c. phase. Besides the variant selection of the crystal orientation was observed during the pahse transformation in the surface of the sheet.
