摘要：The effect of rolling conditions on the microstructure and texture development of twin roll cast ZK60 alloy strips was investigated. Microstructure and texture were measured on specimens subjected to rolling experiments of different thickness reduction per pass. Texture of ZK60 Mg alloy sheets were evaluated by X-ray diffraction method in this study. The (10 (1) over bar0), (0002) pole figures were measured. Tensile test was performed to show the influence of the per pass thickness reduction on mechanical properties. The microstructure of ZK60 alloy sheets consisted of fibrous structure with elongated grains and a relatively density of shear bands along the rolling direction which were warm rolled at 350 degrees C with 10%, 30% and 50% thickness reduction per pass. Dynamic recrystallization could be found during the warm rolling process with different per pass thickness reduction. Grain refinement was found to occur during the warm rolling process, producing a finer grain size of which was warm rolled with 50% reduction in single pass rolling at 350 degrees C. This could result in better mechanical properties.
