Synthesis of nanocomposite material and studying some of its mechanical properties

Abstract EN

This study aims to synthesis a nanocomposite from Al2O3 – Cr2O3 and studying some of its mechanical properties like microhardness and fracture strength. X-Ray diffraction patterns shows a good crystallinity of the composite with very sharp and neat peaks.

TEM photographs shows the good distribution of the particles which have an average particle size of (3-6 nm).

The microhardness is increased with the increasing of sintering temperatures having the height value at 15 % chromia while the fracture strength behaves as a bell shape having again the height value at 15 % chromia.
