Multimodal Analysis of Phases Formed by Reaction Diffusion in Binary Fe-Al System

Popis výsledku v původním jazyce

This work deals with identification possibilities for very fine microstructure phases formed by reaction diffusion in binary Fe-Al system. The Fe-Al samples were prepared by low-pressure cold spray technique using heated air (temperature 300 °C, pressure1.5 MPa) as working gas. Pure Fe and Al powders mixtures were deposited on aluminium substrate. Prepared deposits were subsequently annealed isothermally at temperatures in range from 250 °C to 750 °C for two hours in protective argon atmosphere. Thereafter, phase composition and structure were examined on standard metallographic polished samples. The samples of FeAl elemental mixture in the form of solid cuboids 8x8x4mm were annealed at temperatures from 500 °C up to 750 °C. The general interest in these samples lies in the fact that by solid state or liquid-solid diffusion new intermetallic material with open porous structure is formed. However, the microstructure of the material is generally composed of fine grains or mixtures of ph
