Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

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.

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

Advanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

GROWING WINTER WHEAT IN VARIOUS SHORT-ROTATION CROP ROTATION MODELS ADAPTED TO THE CONDITIONS OF THE STEPPE ZONE OF UKRAINE

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis
The need for developing new models of modern crop rotations is justified by the current conditions of agricultural and economic development. Research conducted in the conditions of the Northern Steppe of Ukraine confirmed the impact of crop rotation ...

Mechanical Alignment of Suprathermally Rotating Grains

The Astrophysical Journal, 1995
It is shown that mechanical alignment of grains can be efficient for grains rotating suprathermally, i.e. with kinetic energy substantially exceeding $k$ (the Boltzmann constant) over any temperature in the system. The paper studies suprathermal rotation caused by H$_{2}$ formation and the alignment that takes place due to crossover events.

ROTATION OF GRAINS OF METAL TIPS (ANNIHILATION OF GRAIN BOUNDARIES)

Le Journal de Physique Colloques, 1986
Experiments in a scanning electron microscope are described which enable in situ studies of the morphological evolution of metal tips (Au). The existence of a rotation of the grains of a polycrystalline tip, which leads to an annihilation of grain boundaries, is directly visualized, measured and interpreted.

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.
