The effect of process factors on formation of rolling and annealing texture of AMg_2 alloy

摘要

The effect of cast method, high-temperature ingot homogenization, reduction distribution in cold roll passes, intermediate annealing conditions, and cold rolling conditions for strip texture of finished size was investigated. An important role of process factors related to ingot production and an insignificant role of the cold rolling rate were found. There is a necessity of correcting the equation of relation between textural parameter and mechanical properties in changing the ingot production process, however inevitable changes of the cold rolling parameters along the length of a coil being rolled do not affect this relation.
