| Abstract: | Doctoral dissertation explores the synthesis and characterization of metastable states within
a novel complex concentrated noble alloy (CCNA) composed of equi-atomic portion of silver
(Ag), palladium (Pd), platinum (Pt), copper (Cu), and nickel (Ni). Completed research activities
enable the understanding of processes and reactions that were crucial in evolution of
thermodynamically metastable microstructures through production of rapidly solidified
ribbons and synthesis of nanoparticles (NP). Two techniques, namely melt spinning and
ultrasonic spray pyrolysis (USP) had been successfully used to achieve homogeneous high
entropy microstructures and were confirmed as suitable for transformation of multiphase
inhomogeneous CCNA microstructures into high entropy ones. Achieved thermodynamically
metastable microstructures enable the achievement of potential functional properties of
selected alloy due to increased surface area and optimized active centres (Ag, Pd, Pt, Cu, Ni)
for catalytic activity.
In the dissertation explained processes and reactions that occurred in the development of the
microstructure of equi-atomic Ag-Pt-Pd-Cu-Ni CCNA during rapid solidification and ultrasonic
spray pyrolysis represent an important contribution to the field of materials science. |
