摘要：

Microcompression specimens, 10-15 mu m in diameter by 20-30 mu m in height, were produced from individual parent grains in a polycrystalline U-13 at.%Nb shape-memory alloy using the focused ion beam technique. The specimens were tested in a nanoindentation instrument with a flat diamond tip to investigate stress-strain behavior as a function of crystallographic orientation. The results are in qualitative agreement with a single-crystal accommodation strain (Bain strain) model of the shape-memory effect for this alloy. (C) 2009 Acta Materialia Inc.
