The dependence of rolling texture on stacking fault energy

Abstract

The transition from the texture, near the ideal orientation {153} 〈112〉, characteristic of pure copper heavily rolled at room temperature to that characteristic of brass {110} 〈112〉 has been examined in a series of alloy systems of known stacking fault energy. It is shown that the fundamental factor governing the change in rolling texture is the decrease in stacking fault energy on alloying and that the {110} 〈112〉 texture is not confined specifically to alloys but is a feature of any material with γ less than about 35 ergs/cm 2, rolled at a temperature not higher than 0.25 T m ; the critical stacking fault energy depends on the rolling temperature. Quenching and irradiation has no appreciable effect on the rolling texture of spec-pure metals and it is concluded that the transition is associated with the difficulty of cross-slip. The possibility of estimating the stacking fault energy from rolling texture is discussed.
