Effect of extrusion parameters on microstructure, texture and mechanical property anisotropy of spray deposited 2195 Al-Li alloy profile

To study the effects of extrusion parameters on the microstructure, texture, and mechanical property of 2195 Al-Li alloy, several extrusion experiments were carried out at different extrusion temperatures and speeds. A profile with different aspect ratios was designed, and the corresponding extrusion die was also designed and manufactured. The effects of aspect ratio, extrusion temperature, and speed on the microstructure and mechanical properties were investigated. The results show that cylindrical fiber grains and strong fiber textures of 111 100 211 311 311 311 , which improves the transverse strength of the profile and reduces the anisotropy.

Automated summary

The study conducted several extrusion experiments on 2195 Al-Li alloy to investigate the effects of extrusion parameters on microstructure, texture, and mechanical properties. The results showed that the formation of cylindrical fiber grains and strong fiber textures improved the longitudinal strength of the profile.
