Texture and residual stresses in the cusn6 alloy subjected to intense plastic deformation

This paper presents the results of analysis of commercial CuSn6 alloy in form of strips at semi-hard state, plastically deformed in the process of repetitive corrugation. The influence of process parameters on the value of residual stresses and texture of examined material was investigated. As a result of residual stress analysis, the presence of compressive stresses for all analysed samples, regardless of the method of plastic working and direction of measurement, was confirmed. The distribution and the value of the stresses depend on the applied deformation process. Texture analysis shows that in the classically rolled strip, in addition to the Brass (110)<112> component, also the Goss (110)<001> and Copper (112)<111> components are present, and their contribution diminishes with the increase in the number of cycles of repetitive corrugation process. After intense plastic deformation the strip is characterised by two distinct texture components, (110)<112> and (110)<111>.
