Despite its important implications for society, predicting corrosion damage has been an elusive goal for scientists and engineers. The application of phase-field modeling to corrosion not only enables tracking the electrolyte–metal interface, but also provides an avenue to explicitly simulate the underlying mesoscale physical processes. This lays the groundwork for developing the first generation of mechanistic corrosion models, which can capture key phenomena such as film rupture and repassivation, the transition from activation- to diffusion-controlled corrosion, interactions with mechanical fields, microstructural and electrochemical effects, intergranular corrosion, material biodegradation, and the interplay with other environmentally assisted damage phenomena such as hydrogen embrittlement.\u0000 \u0000 \u0000 \u0000","PeriodicalId":18828,"journal":{"name":"Mrs Bulletin","volume":null,"pages":null},"PeriodicalIF":5.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141113582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In between these two limits, the solid–liquid interface is morphologically unstable and typically forms cellular-dendritic microstructures, but also other microstructures that remain elusive. Rapid developments in additive manufacturing have renewed the interest in modeling the high-velocity range, where approximate analytical theories provide limited predictions. In this article, we discuss recent advances in phase-field modeling of rapid solidification of metallic alloys, including a brief description of state-of-the-art experiments used for model validation. We describe how phase-field models can cope with the dual challenge of carrying out simulations on experimentally relevant length- and time scales and incorporating nonequilibrium effects at the solid–liquid interface that become dominant at rapid rates. We present selected results, illustrating how phase-field simulations have yielded unprecedented insights into high-velocity interface dynamics, shedding new light on both the absolute stability limit and the formation of banded microstructures that are a hallmark of rapid alloy solidification near this limit. We also discuss state-of-the-art experiments used to validate those insights.\u0000 \u0000 \u0000 \u0000","PeriodicalId":18828,"journal":{"name":"Mrs Bulletin","volume":null,"pages":null},"PeriodicalIF":5.0,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140979101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structurally tunable organic ligands in a two-dimensional (2D) perovskite heterostructure play a central role enhancing the stability and affecting the optical properties. Here, we report the synthesis of ligand-variant 2D perovskite lateral heterostructure nanocrystals, based on the sequential solvent evaporation strategy. The fabricated 2D perovskite heterostructures can tolerate large lattice mismatch in the vertical orientation as much as 16.5 percent. The synthesis strategy can be expanded to various combinations of ligands and halides, yielding a clear interface and tailorable electronic structure.
