摘 要：<正>The effects of an electric field on AIN precipitation and recrystallization texture were investigated. Cold-rolled 08Al killed steel sheets were annealed at 550℃according to the two-step processes, for various maintaining times, with and without applying an electric field. It was found that the electric field promotes the precipitation of the second phase （AIN particles）, strengthens theγ-fiber and weakens theα-fiber texture component in the recrystallized specimens. A possible explanation for the reinforcement ofγ-fiber texture by the electric field is that the second phase AIN particle promotes the growth ofγ-fiber at the expense of differently oriented grains.
