摘要：

Pure Fe-C pearlite was heat-treated and selectively etched to extract [0 0 1]- and [1 0 0]-oriented single crystalline cementite sheets. The elastic properties of the shaped cementite were measured in a simple, in situ bending test system set up inside the scanning electron microscope using a micronewton-range force sensor. The Young's modulus experimentally measured from a single crystal sheet was lower than the value obtained from theoretical calculation. (c) 2014 Acta Materialia Inc. Published by Elsevier Ltd.
