abstract = {The size effect of Ti-6Al-4V submillimeter structures
manufactured by selective laser melting, which is critical
for metallic mechanical metamaterials of unique mechanical
properties, for example, negative Poisson's ratio and
ultrahigh modulus, which show promise in biomedical,
environmental, energy-related applications, has not been
systematically investigated. Presented here are the
quantification of the porosities by X-ray microtomography
scans, texture analysis, and mechanical characterization of
the additively manufactured Ti-6Al-4V microbeams. We found
linearly decreasing porosities, increasing mechanical
properties, and increasing texture in the microbeam with
increasing diameter from 250 to 500 µm. The variation of
microstructure in microbeams of different diameters and
along the sample height, resulting from the printing
parameters and the thermal conditions, leads to the
discrepancy between the behavior observed in experiments and
finite element simulation. Our results provide the
structure-property-processing correlation to improve the
manufacturing and prediction of the mechanical behavior of
metallic mechanical metamaterials.},
