摘要：
Distributions of boundary misorientations measured in an Al-0.13%Mg alloy, processed by equal channel angular extrusion to a von Mises effective strain of 10, have been compared to misorientation distributions generated from a random mix of orientations present in the microstructure. A significant fraction of low angle boundaries is reported and orientation correlation over high angle boundaries is discussed. (C) 2002 Acta Materialia Inc. Published by Elsevier Science Ltd.
