摘要：

The cyclic deformation behavior of a [(1) over bar 4 9] single-slip-oriented Fe-35wt.%Cr alloy single crystals containing fine Cr-rich precipitates was investigated at constant plastic strain amplitude (epsilon(pl)) in the range of 5.0 x 10(-4) to 5.0 x 10(-3) at ambient temperature in air. It was found that the precipitates in these crystals play an important role in cyclic deformation. (C) 2002 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
