Abstract

he present research revolves around the impact of an optimized percentage of silver in vanadium pentoxide (Ag-V 2 O 5 ) expedient for embedding nanofillers in titanium-based super alloys envisaged for boosting the performance of structural materials used in high-supersonic and hypersonic missile surfaces. Bar-like Ag- doped V 2 O s nanofillers fabricated at 1, 3, and 5 % concentrations via microwave- assisted chemical solution technique were investigated for morphological, crystallographic, structural, and compositional properties by employing Field Emission Scanning Electron Microscopy, X-Ray Powder Diffractometry, Vibrational Raman Spectroscopy, and Fourier Transform Infrared Spectrometry. A blend of orthorhombic α- and monoclinic β- phases were identified as spectral fingerprints specific to the Ag-decorated V 2 O 5 crystalline structure. The Williamson-Hall method estimated the average crystallite size of α-Ag 3- VO 4 and β-Ag0.35-V 2 O 5 nanofillers as 31.4 and 29.9 nm, respectively. The best performance of the structural material transpired for the β-Ag0.333-V 2 O 5 phase at 3 % doping with 13.7 nm size, 0.35 % strain, and 4.113 g/cm 3 density.
