Originální abstrakt

Examined FeAl deposits were produced by low-pressure cold spray technique using heated air (300 °C, 1.5 MPa) as working gas. Although metal powders were mixed in ratio 60/40 at.% Fe/Al, the final chemical composition of the 8-10 mm thick deposits changed strongly favouring aluminum (approximately 80 at.% Al). Samples consisting of the deposited material were annealed isothermally in argon protective atmosphere. All annealing processes ran at temperatures from 250 °C to 750 °C for two hours. The overall change of material character during annealing was evaluated: changes in the character of fracture behavior, local micro hardness of the evolving phases and residual powder particles. Microstructure and chemistry of the newly formed phases was evaluated using analytical electron microscopy.
