Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Preemptive biofilm colonization blocks microbial metal corrosion

npj Biofilms and Microbiomes
Sustainable materials are needed to address the serious economic and safety risks of microbial metal corrosion. Colonizing metal surfaces with biofilms of noncorrosive microbes was previously shown to reduce aerobic, abiotic corrosion.

Achieving outstanding heat-resistant properties in Mg alloy via constructing stable solute-network

Materials Research Letters, 2023
A new Mg–Sm–Ce–Mn-based alloying system with a large miscibility gap was uncovered, and multi-solute co-segregations at high-angular grain boundaries (HAGBs), dislocations and low-angular grain boundaries (LAGBs) are obtained after the proper extrusion ...

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

Advanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Giant elastocaloric effect and exceptional mechanical properties in an all-d-metal Ni–Mn–Ti alloy: Experimental and ab-initio studies

Materials & Design, 2019
Exploring novel materials with superior elastocaloric effect (eCE) is a central issue for the development of eCE refrigeration technique. In this work, we report a giant adiabatic temperature change ΔTad of −20.4 K in the 〈100〉-textured all-d-metal ...

(INVITED)Laser-driven white light with tunable low-colour temperature based on novel ZrO2-doped (Gd,Lu)2O3:Eu red-emitting transparent ceramics

Optical Materials: X, 2022
Novel red-emitting ZrO2-doped (Gd,Lu)2O3:Eu transparent fluorescent ceramics were fabricated via a vacuum sintering method. The f–f transitions of Eu3+ in the ZrO2-doped (Gd,Lu)2O3:Eu transparent fluorescent ceramics have much higher intensity than the ...

Functional Texture Design and Texturing Processes

International Journal of Automation Technology, 2016
Various functions can be obtained by applying regular patterns or textures to surfaces. Depending on the function, the required dimensions of the texture, such as the pitch, vary over a wide range: from nanometers for optical function to millimeters for friction.

Slip Localization Intensification Mediated by Grain Boundary Sliding in a Polycrystalline Nickel‐Based Superalloy

Advanced Engineering Materials, EarlyView.
The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy

Advanced Engineering Materials, EarlyView.
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation
