Enhanced grain refinement of commercial pure copper using the ECAE of Al–Cu–Al tri-layer composite
Engineering Science and Technology, an International Journal, 2016 Equal channel angular extrusion (ECAE) is a promising technique for production of ultrafine grained (UFG) materials of few hundred nanometers size. In this research, the grain refinement of copper strip is accelerated to ultrafine range by sandwiching it
