aluminum foil with good profile less than 10 I (the relative differences in elongation of 0.01%) is produced using the profile control system in 1 400 mm cold rolling mill of aluminium strip and foil. Key... and foil are of soft and thin gauge, especially in negative rolling gap. In addition, velocity AGC asks for high system stability and synchronization, so tension AGC takes remarkable function. Because......
metals. The microstructure and microtexture evolutions and grain boundary characteristics of the high purity aluminum (99.998%) processed by ECAP at room temperature are investigated by means of TEM... in high purity aluminum. Microstructure evolution in the high purity aluminum during ECAP is proposed.Key words:equal channel angular processing (ECAP); aluminum; grain refinement; microstructure......
