| dc.description.abstract | This study documents a systematic analysis of the global Schmid factor for different
deformation mechanisms in 0/ and -grains in different forms of direct metal laser sintered
(DMLS) Ti6Al4V(ELI) based on EBSD data. A novelty of this study is the use of these data to calculate
the values of the Schmid factor and the subsequent determination of their distribution and frequency,
which, when compared to the slip systems of crystal structures, helps in determining the favourable
slip systems in play. Both retained -grains and reconstructed prior -grains were considered in this
analysis. The reconstruction of the prior -grains was executed using the Automatic Reconstruction
of Parent Grain for EBSD data (ARPGE) program. The distribution of the global Schmid factor
for these Ti6Al4V phases was calculated using the MATLAB-based MTEX toolbox program. This
analysis of deformation modes in the 0/ -phase was based on a uniaxial load state acting on the
x, y, and z axes, while only the load along the build direction (x-direction) was considered in the
analysis of deformation mechanisms in the -phase of the alloy. The results of this study showed
that the DMLS build direction influenced the distribution of the global Schmid factor for the basal
slip system of 0/ -grains in as-built specimens and those samples that were heat treated below the
! transformation temperature. | en_US |
