Behavior of exterior beam‐column joint reinforced with shape memory alloy

Structural Concrete, EarlyView.
Abstract Beam‐column joints are critical regions in moment‐resisting frames and are particularly susceptible to severe stress concentrations and reinforcement congestion. Conventional design typically relies on dense transverse reinforcement to improve joint performance, resulting in construction difficulties and reinforcement congestion.

3D Liquid Crystal Framework Enclosing Dual Compartments

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
A new type of liquid crystal phase is reported, having the conjugated rod‐like molecular cores form a 3D framework of elongated octahedral cages filled alternatively with alkyl and fluoroalkyl pendant chains. The cages are held together by flexible H‐bonding hinges, making them adaptable to thermal expansion and stable in a wide temperature range.

ELECTRON MICROSCOPE STUDY OF THE MATRIX-MARTENSITE INTERFACE IN Cu-Al-Ni ALLOYS

, 1982
The matrix-martensite interfaces in Cu-Al-Ni shape memory alloys have been examined by means of transmission electron microscopy. Fine parallel striations were observed on both the interfaces between the β1 matrix and γ1' martensite, and the β1 matrix ...

The role of α′-martensite on the variation of compressive residual stress in a gradient nanostructured austenitic stainless steel

Materials & Design
The strain-induced martensitic transformation (α′-martensite) and residual stress (RS) introduction in the gradient nanostructured (GNS) austenitic stainless steel have been extensively reported in the last three decades, however, their correlation is ...

Nanoprecipitate characterisation in NiTi and aluminium alloys: A TEM‐based overview

Journal of Microscopy, EarlyView.
Abstract Nanoscale precipitates are central to the functional and mechanical performance of many advanced alloys, yet their characteristics and spatial distributions can be directly resolved only by electron microscopy. In this poster‐style article, focused ion beam‐prepared TEM lamellae are used to provide a microscopy‐focused overview of ...

Spatial Martensite

, 2016
The spatial distribution of martensite laths at different strained austenite grains has been thoroughly investigated by strain rate variation during tensile deformation of metastable austenitic stainless steel at ambient temperature.
