ABSTRACT

One-dimensional (1D) confined growth nanofiber experience more strain compared to equivalent volume of spherical or cuboid nanoparticles, but the same spherical particle is being consolidated effectively than other morphologies. In consideration of density, the compact can be classified into transparent, dense, and porous ceramics that eventually enables to alter the mechanical properties under stress with respect to grain size and porosity content. Nanostructured bulk ceramic is competent in high strain rate at elevated temperature, although degree of deformation depends on grain size and morphology, and their distribution. In the perspective of structural ceramic research and development, some fundamental and classical mechanical properties are discussed.
