The Effect of Equal-channel Angular Extrusion to the Cast Aluminum Alloy Materials

摘要

With the rapid development of modern world aerospace science and technology, hi-tech weaponry and high-speed transportation tools, industrial production and high-tech equipment manufacturers have increasingly urgent demand for high-performance metal materials. The cast aluminum is a new aluminum alloy series developed by foundry industry recently. Because it does not need the solid solution hardening process and has good mechanical properties, it's loved by the manufacturing sector. This paper targets at channel angular deformation direction to study the cast aluminum tissue material.
