Silver-impregnated Vanadium Pentoxide Nano-fillers apt for
Titanium-based Missile Surfaces
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.
