FeAl alloys; ceramic matrix composites; microstructure; texture; mechanical properties.

Porous ceramic matrix composites FeAlO_𝑦/FeAl_𝑥 with incorporated metal inclusions (cermets) were synthesized by pressureless method, which includes hydrothermal treatment of mechanically alloyed FeAl powder followed by calcination. Their main structural, textural and mechanical features are described. Variation of FeAl powder alloying time results in non-monotonous changes of the porosity and mechanical strength. Details of the cermet microstructure and its relation to the mechanical properties are discussed.
