Article Title: Characteristics of an Aluminum Alloy after Generation of Fine Grains Using Equal Channel Angular Extrusion Process
by S. T. Adedokun and Y. K. Chou

Abstract:
Equal channel angular extrusion (ECAE) was used to generate grains of average size (0.35 um) in an aluminum alloy at room temperature. Also, it was found that the characteristics of the aluminum alloy 1050 (99.5% pure) after using an x-ray diffractometer equipped with texture goniometer was that of a random microtexture. Therefore, it can be concluded from the results obtained that local grain boundary migration, texture evolution and subdivisions in the grains were possible mechanisms involved in the formation of the grain size developed in this work after equal channel angular extrusion process. The work was carried out at the National High Magnetic Field Laboratory, Tallahassee, Florida, USA.
