Modeling and Optimizing of Deformed Steel Bars Hot RollingPeng Zhang; Yunhui Du; Xueping Ren(Material Science and Engineering School, University’ of Science and Technology’ Beijing, Beijing 100083)摘 要: of hot rolled AZ31 Mg alloy sheets were studied to understand the microstructure evolution during AZ31 Mg alloy hot rolling process. The roller was heated to 180 ℃ with burning hydrogen... microstructures are greatly refined and mechanical properties are improved. The fine grains of about 4 μm were obtained of the final 0.9 mm sheets.

analysis during hot extrusion and cold rolling process[9, 10] were carried out in order to explore the strengthening mechanism associated with texture. It was revealed that the matrix plastic deformation... and revealed that the final cold rolling textures was rather alike[19]. The reason could be attributed to the weak textures produced during hot extrusion process. 4 CONCLUSIONS Finite element......
