Experimental measurement of Young’s modulus from a single crystalline cementite

Pure Fe–C pearlite was heat-treated and selectively etched to extract [001]- and [100]-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 micronewto...

Zusammenfassung:Pure Fe–C pearlite was heat-treated and selectively etched to extract [001]- and [100]-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.
