THE FORMATION OF CUBE VOLUMES IN COLD-ROLLED FCC METALS

It has recently been reported that in cold rolled copper, cube-oriente d volumes are frequently found in long thin bands next to bands whose orientation is related to the cube orientation by a 30-40 degrees rota tion about a <111> common pole. This microstructure would suggest that during recrystallisation, cube in the deformed structure can growth e asily into its neighbour due to the special misorientation which allow s a high boundary migration rate. The formation of this special micros tructural arrangement is studied here by a generalised deformation ban ding model.
