摘要：

A variational estimate for non-linear composite deformation is specialized to provide a simple estimate of uniaxial steady-state creep rates in microcellular metals deforming by power-law creep knowing their linear modulus. Resulting expressions compare well with previous theory and data. (c) 2007 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
