Originální abstrakt

In the Ni _Al binary system, the majority of scientific attention is focused on the development of NiAl and Ni3Al phases. These phases have a great potential in high temperature applications. The Ni _Al binary system also contains other three, less known phases. The NiAl3, Ni2Al3 and Ni5Al3 phases are not considered for use in high-temperature applications mainly due to their lower melting points being 854 degree C, 1133 degree C and approx. 700 degree C, respectively. New information about their formation and degradation mechanisms, morphology, and distribution, physical and mechanical properties can be, however, successfully used for strengthening of Al composites, Ni/Al/Ni interconnections, and layered structures design. This contribution is focused on local mechanical properties of Al substrate and strengthening Al-rich intermetallic phases produced from deposited Ni sacrificial coatings after the annealing in a wide range of temperatures encompassing the solid and/or molten state of the aluminium substrate.
