Infulence of recrystallization on damping properties of alloy Fe75Zr4Ti3B17Cu1

It is expected that damping in amorphous metals change after its recrystallization. For this purpose study of this phenomena was investigated. An alloy Fe₇₅ Z r₄Ti₃B₁₇Cu₁ was manufactured in a very specific conditions to obtain amorphous structure. To confirm structure of the manufactured material basic testing was conducted including XRD, AFM, LFM and SEM with EDS attachment. The study showed that the structure in fact is partially amorphous and partially nanocrystalline. To determine expected change of damping sample in form of rod was tested for bounce height in controlled conditions before and after heat treatment that changed materials structure. Obtained results indicate decrease of damping after heat treatment and therefore confirms initial assumption.
