Paper Title:
Fracture and Crystallographic Phase Correlation in Alumina Based Particulate Composites
  Abstract

The paper deals with the results of mechanical properties and microstructure investigations performed in two composite systems: Al2O3/WC and Al2O3/W. The fracture toughness measurements were made for materials characteristics. Microstructure of composites was thoroughly investigated using transmission and scanning electron microscopy. Selected Area Electron Dffractions (SAEDs) as well as Electron Backscatter Diffractions (EBSDs) were applied to establish crystallographic relationships between neighboring grains of different phases both in a local and global scale. Examples of orientation maps and stereographic projections for different crystallographic directions as well as orientation relationships between different phases (alumina and reinforcing inclusions) were shown and described.
