Effect of the addition of Sc element on the microstructure and properties of Al80Li5Mg5Zn5Cu5 high-entropy alloy by Zhiqiang Li, Weili Wang, Xuanqi Chen, Bo Peng, Hui Xing, Jieren Yang

“…It was found that after minor alloying with Sc, a new strengthening precipitate phase (Al₃Sc) appeared in the alloy, which effectively inhibited grain growth, reducing the average grain size of Al₈₀Li₅Mg₅ Zn₅Cu₅ from 548.2 μm to 28.4 μm, significantly refining the grain structure. …”

Study on the Effect of Mineral Particle Sizes on the Spectral Characteristics of Sound and Vibrations in Rock Drilling by Zhantao Li, Sui Wang, Jicheng Wang, Chunxia Song, Bin Chen

“…The time-domain features of sound and vibration, such as the amplitude of sound pressure and vibration, are important indexes that roughly reflect grain sizes. The general trend is that the larger the amplitudes of sound and vibration, the larger the grain size. …”

Mechanisms of plastic instability and fracture of compressed and tensile tested Mg-Li alloys investigated using the acoustic emission method by A. Pawelek, A. Piatkowski, W. Wajda, W. Skuza, A. Tarasek, W. Ozgowicz, B Grzegorczyk, Z. Ranachowski, S. Kúdela Jr, S. Kúdela

“…The main aim of the paper is to investigate, to determine and to explain the possible influence of factors related with enhanced internal stresses such as: segregation of precipitates along grain boundaries or solute atoms along dislocations (Cottrell atmospheres) or dislocation pile-ups at grain boundaries which create very high stress concentration leading to fracture. …”

Wheat NAC transcription factor NAC5‐1 is a positive regulator of senescence by Catherine Evans, Sophie Louise Mogg, Charline Soraru, Emma Wallington, Juliet Coates, Philippa Borrill

“…Abstract Wheat (Triticum aestivum L.) is an important source of both calories and protein in global diets, but there is a trade‐off between grain yield and protein content. The timing of leaf senescence could mediate this trade‐off as it is associated with both declines in photosynthesis and nitrogen remobilization from leaves to grain. …”
