dc.description.abstract | Strain-rate sensitivity (SRS) of high-Mn austenitic steels at the micrometric scale was investigated. Compressive-deformation response of TWIP steel micropillars demonstrated negative SRS between 1x10(-4)and 1 s(-1)strain rates, which was terminated by the formation of nanotwins that significantly enhance the work-hardening capacity at 1 s(-1). | |

The FIB and TEM were conducted at Bilkent UniversityUNAM facilities, and the rest of the experiments were carried out at the facilities of Koc Uni-versity Surface Science and Technology Center (KUYTAM).Figure 3.(a) TEM image evidencing nanotwin formation in the micropillar deformed at 1 s−1strain rate, (b) close-up of the nanotwins detected in (a), and (c) the corresponding selected-area diffraction (SAD) pattern.PHILOSOPHICAL MAGAZINE LETTERS511 | |
