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 …

Contrary to the characteristic strengthening of polycrystalline ceramics with a decrease in
grain size, extremely fine nanocrystalline ceramics exhibit softening, increased plasticity and …

Nanosintering behaviour of MgAl2O4 ultra-fine powder was investigated under high
pressure. We found that the nanosintering mechanism under high pressure was quite …

Magnesium aluminate spinel (MgAl2O4) is known for its excellent deformation behavior at
high temperatures. By retaining nanocrystalline grain size after densification, the extent of …

Nanoindentation tests were performed on nanostructured transparent magnesium aluminate
(MgAl 2 O 4) ceramics to determine their mechanical properties. These tests were carried …

Magnesium aluminate nanoceramics show superior hardness due to an extension of the
Hall-Petch relationship down to grain sizes below 10 nm. However, the manufacturing of …

Synthesis of nanocrystalline magnesium aluminate spinel (MgAl2O4) by mechanical
activation of a powder mixture containing Al2O3 and MgCO3 with subsequent annealing …

Transparent Mg Al 2 O 4 spinel nanoceramics have been sintered at relatively low-
temperature (500–700 C⁠) under high pressure (2–5 GPa) using a hydrostatic press with …

Nanoceramics may have different structural and physical properties compared to their
coarse-grained counterparts. Here, we report the high-pressure study of micro-and nano …

At room temperature, in situ nanoindentation experiments in a transmission electron
microscope reveal the grain and grain boundary activities in fully dense ceramic …
