Název v původním jazyce

Morphology of Spinels and Al2O3 Particles in an Al2O3/Al-Mg-Si Composite Material Revealed by Scanning Low Energy Electron Microscopy

Popis výsledku v původním jazyce

In metal matrix composite materials consisting of oxide particles and Al alloys, including Mg as a solute atom, MgAl2O4 spinels are formed at the interface between the particles and the matrix. In the present study, the scanning low energy electron microscopy (SLEEM) method has been applied to confirm morphologies of .alpha.-Al2O3 particles and MgAl2O4 spinel crystals grown on the alumina particles in the Al2O3/Al-1.0mass% Mg2Si alloy composite material. The morphology of .alpha.-Al2O3 particles beforefabrication of the composite material was like a facetted barrel with 2 hexagonal {0001} and 6 trapezoidal {1101} planes. Spinels were formed on facets of Al2O3 as small particles, and their shape was an octahedron consisting of 8 equiaxial triangles. Mutual orientation between spinels and alumina particles, established in our recent TEM study, was fully confirmed.
