Název v původním jazyce

SLEEM study of MgAl2O4 at interface between Al2O3 and matrix in Al2O3/Al alloy composite materials

Popis výsledku v původním jazyce

In the present paper, MgAl2O4 in the Al2O3/Al-1.0mass%Mg2Si alloy composite was observed by a scanning electron microscope equipped with the low energy electron (SLEEM) adaptation aiming at examination of its morphology and orientation relationships to the Al2O3 particles. Owing to its much smaller interaction volume of signal exciting electrons in the target and hence more localized information, together with a favorable combination of secondary (SE) and backscattered (BSE) electron signals, the SLEEMmethod provided much better readable and detailed images of all particles, their shapes and mutual orientations, in comparison with conventional SE and BSE images at the electron energies usually used in the SEM. MgAl2O4 (spinels) were formed on facets of Al2O3 as small particles, and their shape well corresponded to an octahedron consisting of 8 equiaxial triangles.
