The results show that the main texture component {100}<011> becomes stronger with the increase of hot rolling reduction. The cold rolling textures are composed of typical "copper type" texture components C {112}<111>, S {123}<634>, R/S {124}<211>, B {110}<112> and G {110}<001>, the orientation intensities increase with increasing cold rolling reduction. Compared to the conventional cold rolling with the same amount reduction, the transverse rolling reduces the orientation intensities of each cold rolling textures components, and strengthens the {001}<110> and {110}<uvw> texture components. During cross shear rolling process, notable difference of intensity of cold rolling textures components were observed from the slow roller side to the fast roller.展开更多

The objective of this study is to clarify how much the crossing rolling process procedure affects the microstructure, texture and mechanical property of this type of materials. This experiment begins from the power metallurgy to the final molybdenum strip (0.15mmxlOOmmx2000mm) through the cross rolling processing procedure. As a result, good mechanical property, improved elongation, enhanced ductility for further process, such as deep drawing and punching, and the reduced difference of the strength and plasticity between the parallel to rolling direction and perpendicular to rolling direction are achieved by the cross rolling processing procedure. According to discussing all the details about this experiment, it is confirmed that cross rolling molybdenum sheet can provide a concise and comprehensive explanation of processes and can guarantee the optical mechanical property and suitable for large production.展开更多
