Effect of Cr on the microstructure and corrosion behavior of nickel-based alloys in hydrochloric acid

Journal of Materials Research and Technology, Год журнала: 2024, Номер 32, С. 2867 - 2881

Nickel-base alloy is a type of metal material with excellent properties and widely used in many fields. However, the harsh environment acid solution, corrosion causes reduction service life alloys, thereby limiting alloys' use development. In this paper, effect Chromium (Cr) content on microstructure behavior nickel-based alloys hydrochloric (HCl) was studied by scanning electron microscopy (SEM), energy dispersive spectrum (EDS), backscatter diffraction (EBSD) electrochemical workstation. Meanwhile, X-ray photoelectron spectroscopy (XPS) to investigate composition surface passive films. For Cr20 Cr30 single face-centered cubic (FCC) structure, Cr2O3 films increased Cr content, effectively improving resistance. As continued increase, second phases having body-centered (BCC) lattice were precipitated both Cr40 Cr50 samples, inducing microgalvanic corrosion, thus deteriorating XPS results showed that, alloy, relative bound water highest, indicating that its film had best film, pitting resistance related appropriate improved

New-Generation Materials for Hydrogen Storage in Medium-Entropy Alloys

Materials, Год журнала: 2024, Номер 17(12), С. 2897 - 2897

Опубликована: Июнь 13, 2024

This study presents the design, preparation, and characterization of thirty new medium-entropy alloys (MEAs) in three systems: Al-Ti-Nb-Zr, Al-Ti-Nb-V, Al-Ti-Nb-Hf. The hardness ranged from 320 to 800 HV0.3. Among studied, Al15Ti40Nb30Zr15 exhibited highest-reversible hydrogen storage capacity (1.03 wt.%), with an H/M value 0.68, comparable LaNi5, but a reduced density (5.11 g·cm−3) without rare earth elements. further reveals strong correlation between absorption/desorption; higher is responsible for uptake. finding highlights interplay material’s properties behavior MEAs, has implications development efficient materials.
