Grain size effect on the mechanical properties of nanocrystalline magnesium aluminate spinel
To develop transparent materials with superior mechanical properties, nanocrystalline
magnesium aluminate (MgAl 2 O 4) spinel with grain sizes ranging from 3.7 to 80 nm has
been synthesized by environmentally controlled pressure assisted sintering. In this study, we
investigated the microstructure and grain size dependence of the mechanical properties of
nanocrystalline MgAl 2 O 4 by performing transmission electron microscopy,
nanoindentation, uniaxial micropillar compression, and micro-cantilever bending. Electron …
