Modeling and Simulation of Microstructure Evolution for Additive Manufacturing of Metals: A Critical Review

open access: yesMetallurgical and Materials Transactions. A, 2020
Beam-based additive manufacturing (AM) of metallic components is characterized by extreme process conditions. The component forms in a line-by-line and layer-by-layer process over many hours.

The Microstructure of (t, m, s)-Nets

open access: yesJournal of Complexity, 2001
In an article of \textit{A. B. Owen} [J. Complexity 14, 466-489 (1998; Zbl 0916.65017)] the question about the distribution properties of digital \((t, m, s)\)-nets in small intervals was raised. The authors give an algebraic expression as well as upper and lower bounds for the maximum number of points of a \((t, m, s)\)-net in these intervals and also

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

open access: yesAdvanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Multiscale Modeling of Process‐Induced Defects in Fused Filament Fabrication‐Printed Materials

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents a predictive multiscale modeling tool for defect analysis of fused filament fabricated‐printed materials and their performance prediction using a mechanistic data science‐based reduced‐order modeling approach. Process‐induced defects are inherent to additively manufactured parts and significantly influence the performance of printed

Sub-nanometer ultrathin epitaxy of AlGaN and its application in efficient doping

open access: yesLight: Science & Applications, 2022
A desorption-tailoring strategy is demonstrated to steadily prepare self-assembled p-AlGaN superlattices with sub-nanometer ultrathin barriers by MOCVD, which juggle the hole concentration and transport.

Ice microstructures and microdynamics [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2017
Ice occurs as polycrystalline aggregates in which the bulk behaviour is the result of the behaviour of the ensemble of individual grains, and is therefore dependent on the microstructure, that is to say, the whole arrangement of grains (size, shape, and shape and lattice orientations ...
