Abstract

The microstructure and mechanical properties of 2A50 al loy under different extrusion ratios were investigated. The results showed that the grain of the alloy was refined

microstructure in longitudinal direction was elongated

the casting defects were eliminated and the mechanical properties we re ascended with increase in extrusion ratio.
