摘要：

Mechanical testing of micron-size samples provides distinct advantages over macroscopic testing for quantifying the fundamental processes governing plastic flow, such as the exploration of intrinsic size effects and direct, quantitative measures of strain heterogeneity and intermittency. Future advances include an expanded range of testing and data acquisition parameters, including spatially-localized displacement measurements. (c) 2005 Acta Materialia Inc. Published by Elsevier Ltd.
