Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Podem os dispersantes afetar as propriedades dos concretos refratários após a queima? Could the dispersants affect the properties of refractory castables after firing?

Cerâmica, 2009
A aplicação de concretos refratários é um processo em constante evolução e apresenta uma forte dependência dos avanços dos conhecimentos sobre os ligantes hidráulicos.

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

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.

Tendência à hidratação do pó de alumínio em concretos refratários contendo elevado teor de carbono Hydration of aluminum powder in high-carbon containing refractory castables

Cerâmica, 2004
Os benefícios proporcionados pela adição de carbono em concretos refratários têm ampliado a utilização desses materiais em aplicações siderúrgicas. Contudo, um problema inerente à utilização de carbono em refratários é a sua susceptibilidade à oxidação a

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Resistência à erosão de concretos refratários de alta alumina nanoligados Erosion resistance of nanobonded high-alumina refractory castables

Cerâmica, 2011
A avaliação do emprego de concretos refratários nanoligados em aplicações onde ocorre desgaste por erosão é de importante interesse devido aos estudos recentes que indicam esta rota como uma alternativa à substituição do cimento de aluminato de cálcio ...

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.
