Investigation on Metal Flow Behavior in Compression of Aluminum Alloy L-Shaped Billets
The metal deformation behavior of 7075 aluminum alloy L-shape ring was investigated by numerical simulation,and the influence of billet shape on the plastic deformation was analyzed.The results show that the shape factors of billets have a great influence on metal flow behavior.With the increase of high-radius ratio,the uniformity of deformation increases;with the increase of deformed area and the deformed trend of bulge of billets,the complex degree of metal flow behavior increase,so that it provides a better scientific basis for compression deformation of the 7075 aluminum alloys L-shaped billets.
