The Effect of Grain Refiner on Aluminium Filtration
, 2021 Grain refinement of aluminium and its alloys is a common industrial practice. Fine equiaxed, grain structure leads to improved castability, strength, machinability, formability, and good surface finish. Filtration is one of the widely used technologies to remove inclusions from the melt.

Adaptive Coarse Graining, Environment, Strong Decoherence, and Quasiclassical Realms [PDF]
Phys. Rev. A 89, 052125 (2014), 2013 Three ideas are introduced that when brought together characterize the realistic quasiclassical realms of our quantum universe as particular kinds of sets of alternative coarse-grained histories defined by quasiclassical variables: (1) Branch dependent adaptive coarse grainings that can be close to maximally refined and can simplify calculation.

Review on Grain Refinement of Metallic Materials to Regulate Cellular Behavior
Metals, 2022 Metallic materials have been widely used as orthopedic implants in clinics for their good mechanical, physical, and chemical properties, but their slow osseointegration rate is still one of the main issues causing implantation failure.

The grain refinement potency of bismuth in magnesium
Journal of Alloys and Compounds, 2017 AbstractA quantitative model was applied to analyse the grain refinement potency of bismuth in magnesium. The efficiency of the grain refiner was identified through the analysis of grain size vs inverse of the growth restriction factor (Q) plots, with a comparison of the Zr solute under similar experimental conditions.

Effects of grain refinement on cast structure and tensile properties of superalloy K4169 at high pouring temperature [PDF]
China Foundry, 2016 In order to improve the filling ability of large complex thin wall castings, the pouring temperature should be increased, but this will result in the grain coarsening. To overcome this problem, two kinds of grain refiners of Co-Fe-Nb and Cr-Fe-Nb ternary

Contrastive Bootstrapping for Label Refinement [PDF]
arXiv, 2023 Traditional text classification typically categorizes texts into pre-defined coarse-grained classes, from which the produced models cannot handle the real-world scenario where finer categories emerge periodically for accurate services. In this work, we investigate the setting where fine-grained classification is done only using the annotation of coarse-

Metallurgical and Materials Transactions. A, 2020 Surface deformation, applied in-process by machine hammer peening (MHP), has the potential to refine the coarse columnar β -grain structures normally found in high deposition rate Wire-Arc Additive Manufacturing (WAAM) processes with Ti alloys like Ti ...
