the cross wedge rolling technology, as an effective method of shaft forming, has been paid more and more attention. With the development of the car's lightweight, aluminum alloy with its high quality performance, as a substitute for the best choice of structural steel. Steel of shaft parts by cross wedge rolling technology by both foreign and domestic experts and scholars research and practical production experience accumulation, has perfected a process, but because of the aluminum alloy metal microstructure and properties, structure and deformation characteristics are iron and steel has a big difference, and cross wedge rolling in the rolling process, the deformation of workpiece complex, the materials of different makes the selection of process parameters is not the same, so in this paper, the research on aluminum alloy wedge cross rolling process and organizational performance, forming of aluminum alloy workpiece and deformation of understanding have important significance.

Study on the internal flow law of cross wedge rolling of aluminum alloy based on finite element analysis
