Microstructure-Corrosion Property Correlation in Electrodeposited Sn and Cu Based Coating Systems
Conventional metallic coatings are widely used for protection against corrosion. This study investigates the correlation between microstructure and corrosion properties in SnCr and CuCr electrodeposited coatings. The wide ...
Uniaxial Fatigue Behavior of Freestanding Platinum-Aluminide (PtAl) Bond Coat
Pt-aluminide (PtAl) bond coat is used as a part of Thermal Barrier Coating (TBC) system on Ni-base superalloy components in advanced gas turbine aeroengines. The thickness of B2-NiAl intermetallic based diffused coating ...
Understanding deformation mechanisms in the Hall-Petch breakdown regime of Ni-W alloys
The substantially higher strengths of nanocrystalline metals has been to attributed to the well-known Hall-Petch relationship σ= σ_o+k_HP d^(-1/2) where 𝜎 is the yield stress, 𝜎𝑜 is the lattice friction stress, 𝑑 is ...
Bioinspiration for battling bacteria: Nature inspired high aspect ratio nanostructures for new age antibacterial surfaces
Bacterial colonization and biofilm formation on abiotic surfaces effectuate corrosion,
fermentation, and infection resulting in tremendous economic and human losses each year.
Aggravating the situation, new multi-drug ...
High-Throughput Bending Tests for Investigating Creep Behavior Affected by Structural and Microstructural Inhomogeneities
The bending of cantilevers is an alternate technique for the extraction of power-law creep parameters of materials. It has been shown earlier that in homogeneous systems showing tension-compression symmetry, digital image ...
Inkjet-printed high performance oxide electronics and its application at sensor interfaces
Over the last two decades, printing of oxide semiconductors has received special attention due to its advantages such as low processing temperature, even at room temperature; high electron mobility; good transparency due ...
Thermoplastic epoxy designed using Vitrimer chemistries
Globally, 70 million tons of epoxy thermosets are manufactured at a perplexing rate which constitutes approximately a quarter of polymer generation by weight. A thermosetting polymer contains a permanent crosslinked network ...
Effect of thermo-mechanical treatment on the evolution of microstructure and mechanical properties in a β and a β rich α+β titanium alloy
Near β and metastable β-titanium alloys are difficult to process due to narrow processing window. Lower processing temperature causes difficulty in recrystallization of these alloys especially in the two phase conditions, ...
