Effects of mechanical stress, chemical potential, and coverage on hydrogen solubility during hydrogen-enhanced decohesion of ferritic steel grain boundaries: A first-principles study

Abril Azócar Guzmán and Rebecca Janisch

Phys. Rev. Materials 8, 073601 (2024) - Published 1 July, 2024

Hydrogen embrittlement severely impacts structural materials such as iron and its alloys. This study aims to understand hydrogen-enhanced decohesion in ferritic steel grain boundaries (GBs). Density functional theory calculations are carried out to investigate the influence of H on the decohesion of the $Σ$ 5(310)[001] and $Σ$ 3(112)[1-10] symmetrical tilt GBs in body-centered cubic (bcc) Fe and Fe+ $X$ systems, where $X$ = C, Cr, V, or Mn. The findings indicate that higher local concentrations of hydrogen significantly reduce GB cohesive strength, especially at the $Σ$ 5 GB. However, at finite stress, the $Σ$ 3 GB becomes more favorable for hydrogen segregation, suggesting hydrogen redistribution due to stresses in the microstructure can enhance hydrogen resistance.

Deformation and failure of glassy polymer-polymer interfaces compatibilized by linear multiblock copolymers

Ryan P. Collanton and Kevin D. Dorfman

Phys. Rev. Materials 8, 075604 (2024) - Published 16 July, 2024

When two different polymers are blended, they form phase-separated emulsions with weak interfaces. These recycled materials are inferior to the original plastics, posing a fundamental challenge for recycling mixed plastic waste streams. An emerging solution to this problem is the addition of a multiblock copolymer compatibilizer to “stitch together” the interface. Using coarse-grained molecular dynamics simulations, Collanton and Dorfman examined how interfacial toughness is impacted by the number of blocks in the compatibilizer and the copolymer loading, connecting the microstructural features of the interface to its failure mechanism.

Two-step aging dynamics in enzymatic milk gels

Julien Bauland, Gouranga Manna, Thibaut Divoux, and Thomas Gibaud

Phys. Rev. Materials 8, L072601 (2024) - Published 9 July, 2024

In this study, the authors take advantage of the emergence time-resolved mechanical spectroscopy to investigate the formation and aging of enzymatic milk gels, made of soft natural colloids. By coupling rheometric measurements with structural characterizations, they reveal two sequential steps in the aging process. First, the open particulate network rapidly matures into a compact network, increasing gel elasticity and evolving the viscoelastic spectrum. Second, the microstructure “freezes” at a critical time, after which aging proceeds through contact-driven mechanisms. This two-step aging process is crucial for industrial cheese processing and contrasts with the aging of hard particle colloidal gels, where the overall network structure remains constant throughout aging.

Effects of dimensionality on the electronic structure of Ruddlesden-Popper chromates ${Sr}_{n + 1} {Cr}_{n} O_{3 n + 1}$

Phys. Rev. Materials 8, L071602 (2024) - Published 18 July, 2024

Oxide molecular beam epitaxy is a powerful synthesis technique capable of creating complex layered structures with elements in high oxidation states. The authros start with the Sr $_{n + 1}$ Cr $_{n}$ O $_{3 n + 1}$ Ruddlesden-Popper series. This system contains the magnetic Cr $^{4 +}$ cation which gives rise to electronic correlations that vary as a function of structural dimensionality: Sr $_{2}$ CrO $_{4}$ and Sr $_{3}$ Cr $_{2}$ O $_{7}$ possess enhanced spin and orbital ordering temperatures compared to the SrCrO $_{3}$ end member. In this work, they synthesize films for $n = 1$ to $n = 5$ , uncovering a metal to insulator transition. They seek the physical origins of the concomitant spin and orbital orderings – both experimentally with x-ray absorption spectroscopy measurements, and theoretically with density functional theory calculations. Their results unveil the basis of these exotic ground states, including additional structural distortions that play a key role in the system and enable the metal-insulator transitions.
