Hydrogen Bonds00:26

Hydrogen Bonds

120.8K
Hydrogen bonds are weak attractions between atoms that have formed other chemical bonds. One of these atoms is electronegative, like oxygen, and has a partial negative charge. The other is a hydrogen atom that has bonded with another electronegative atom and has a partial positive charge.
Hydrogen Bonds Control the World!
Because hydrogen has very weak electronegativity when it binds with a strongly electronegative atom, such as oxygen or nitrogen, electrons in the bond are unequally shared....

Precipitation and Co-precipitation

1.7K
Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...

Corrosion02:49

Corrosion

23.7K
The degradation of metals due to natural electrochemical processes is known as corrosion. Rust formation on iron, tarnishing of silver, and the blue-green patina that develops on copper are examples of corrosion. Corrosion involves the oxidation of metals. Sometimes it is protective, such as the oxidation of copper or aluminum, wherein a protective layer of metal oxide or its derivatives forms on the surface, protecting the underlying metal from further oxidation. In other cases, corrosion is...

Extraction: Advanced Methods

420
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Colors and Magnetism

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Area of Science:

  • Materials Science
  • Metallurgy
  • Computational Materials Science

Background:

  • Copper (Cu) in steel serves dual roles: a residual element causing processing issues and an alloying element enhancing properties like corrosion resistance and hardenability via nanosized precipitates.
  • The drive towards a green economy necessitates increased steel recycling and the adoption of alternative energy carriers like hydrogen, which poses a significant risk of hydrogen embrittlement (HE) in high-strength steels.

Purpose of the Study:

  • To investigate copper precipitates as a strategy to mitigate hydrogen embrittlement (HE) in high-strength steels.
  • To explore the hydrogen trapping behavior at copper/iron interfaces across different copper precipitate structures.

Main Methods:

  • Employed systematic density functional theory (DFT) calculations to model hydrogen interactions with Cu/Fe interfaces.
  • Utilized thermodynamic calculations to assess the potential of different precipitate structures in mitigating HE.

Main Results:

  • Hydrogen binding energy at Cu/Fe interfaces increased along the precipitation sequence from body-centered cubic (bcc) to 9R to face-centered cubic (fcc) structures, ranging from -0.05 to -0.18 eV.
  • Identified that while hydrogen trapping by Cu precipitates is relatively weak, similar to dislocations, fcc Cu precipitates show potential for HE mitigation.

Conclusions:

  • Face-centered cubic (fcc) copper precipitates are identified as the most desirable structure for mitigating hydrogen embrittlement in steels.
  • These fcc Cu precipitates can help reduce the likelihood of the hydrogen-enhanced localized plasticity (HELP) mechanism, a key factor in HE.
