This thesis focuses on the plasticity of Fe-Mn-C twinning-induced plasticity steel micro-pillars
purposely oriented for different deformation mechanisms and the nature of strengthening …

Deformation twinning contributes to a high work-hardening rate through modification of the
dislocation structure and a dynamic Hall-Petch effect in polycrystalline steel. Due to the well …

Bulk and micro-pillar single crystals were used to investigate the twinning-induced plasticity
mechanism in austenitic Fe-22 wt% Mn-0.6 wt% C TWIP steel. Compression of micro-pillars …

We unravel the nature of twin boundary-associated strengthening in Fe-Mn-C twinning-
induced plasticity steel (TWIPs) by micro-pillar compression tests. Dislocation interactions …

Deformation twinning and dislocation slip in twinning-induced plasticity (TWIP) steels have
been shown to depend strongly on the crystal orientation, yet the underlying mechanism is …

The micro-scale plastic deformation behavior of an austenitic Fe-1.2% C-7.0% Mn (in wt%)
steel was studied by means of nano-indentation and in situ compression of micro-pillars with …

Eliminating the interference of grain boundary, grain size and grain orientation, the effect of
pure nanoscale ordered phases with Pt 2 Mo-type structure on the micro-mechanical …

Mechanical twins are found to nucleate and grow in submicron-to micron-sized pillars of a
twinning-induced plasticity steel under compression. The twin thickness ranges from …

Copper and α-brass micropillars containing a single coherent twin boundary of controlled
orientation were compressed to systematically investigate dislocation-twin boundary …

Micro pillar compression testing has been performed on bcc iron single crystals to determine
the mechanical properties and deformation mechanisms and their dependency on size and …
