Advanced Science, EarlyView.Cryogenic cooling induces an orthorhombic‐to‐monoclinic phase transition in CsPbBr3 quantum dots, accompanied by pronounced strain localization at surfaces and interfaces. Multimodal in situ STEM directly visualize reversible defect healing during moderate cryogenic treatment and irreversible degradation upon prolonged exposure, revealing the intrinsic

Advanced Science, EarlyView.By integrating simulations and experiments, the preferred (001) crystallographic texture promotes reversible martensite formation through variant selection, enhancing both superelastic and elastocaloric performance. This work provides fundamental guidelines for designing high‐efficiency NiTi‐based functional materials. Abstract Developing elastocaloric

A sharp interface model for the propagation of martensitic phase boundaries [PDF]
, 2008 A model for the quasistatic evolution of martensitic phase boundaries is presented. The model is essentially the gradient flow of an energy that can contains elastic energy due to the underlying change in crystal structure in the course of the phase ...

Disorder-Driven Pretransitional Tweed in Martensitic Transformations
, 1995 Defying the conventional wisdom regarding first--order transitions, {\it solid--solid displacive transformations} are often accompanied by pronounced pretransitional phenomena.

Materials and Corrosion, EarlyView.The findings presented in this manuscript recommend the Ti‐22Zr‐11Nb‐2Sn alloy as a possible alternative to Nitinol for use in biomedical devices, especially in the large‐scale manufacturing of self‐expandable vascular stents used in angioplasty. ABSTRACT Nowadays, for applications such as coronary stents, the most widely used materials are Nitinol or ...

Lavrentiev Phenomenon in Microstructure Theory [PDF]
, 1996 A variational problem arising as a model in martensitic phase transformation including surface energy is studied. It explains the complex, multi-dimensional pattern of twin branching which is often observed in a martensitic phase near the austenite ...

Phase field simulations of coupled phase transformations in ferroelastic-ferroelastic nanocomposites
, 2009 We use phase field simulations to study composites made of two different ferroelastics (e.g., two types of martensite). The deformation of one material due to a phase transformation can elastically affect the other constituent and induce it to transform ...

Materials and Corrosion, EarlyView.The corrosion performance of X12CrMoWVNbN10‐1‐1 steel in chloride environments dramatically depends on pH. Acidic conditions trigger intense surface degradation, whereas neutral and alkaline media foster the formation of a compact and stable passive film, drastically reducing both general and localized corrosion.

MetalMat, EarlyView.This study reports the electroforming of Fe thin foils using ChCl/urea DES. It analyzes the effect of current density and MnCl2 addition in the electroformed samples’ composition and corrosion behavior. It presents new insights into Mn incorporation via Fe₂O₃ doping in the Fe matrix.
