Hot Cracking Mechanisms in Welding Metallurgy: A Review of Theoretical Approaches
MATEC Web of Conferences, 2018 Hot cracking often refers to the appearance of liquid films along grain boundaries or to another place in the weld metal structure. Despite hot cracking importance in alloy weldability, there is limited understanding of the influencing mechanisms ...

Advanced Science, EarlyView.Two‐dimensional CuInP2S6 nanosheets are incorporated into a P(VDF‐TrFE) matrix to induce polarization‐cooperative ferroelectric coupling. The resulting P(VDF‐TrFE)/CuInP2S6 hybrid film exhibits reinforced ferroelectric ordering and reduced coercive electric fields compared with pristine P(VDF‐TrFE).

Advanced Science, EarlyView.Through a mixed‐ligand strategy that precisely regulates pore size and framework polarity, the Xe adsorption behavior is transformed from flexible to near‐rigid. ZIF‐7‐Cl(20) achieves sensitive recognition, efficient capture, and high selectivity for Xe, enabling high‐efficiency separation from Xe/Kr mixtures.

Weldability of High Alloys [PDF]
, 2003 The purpose of this study was to investigate the effect of silicon and iron on the weldability of HAYNES HR-160{reg_sign} alloy. HR-I60 alloy is a solid solution strengthened Ni-Co-Cr-Si alloy. The alloy is designed to resist corrosion in sulfidizing and other aggressive high temperature environments.

Chiral Morphing of Liquid Crystal Polymer Networks
Advanced Science, EarlyView.This paper reviews how macroscopic chirality spontaneously arises from liquid crystal polymer materials. It describes how alignment is utilized to create the mechanical anisotropy, geometric misorientation and asymmetry that leads to chiral shape morphing, how shape selection between helicoids and helices arises, the techniques used to prepare these ...

Electropulse‐Driven Dislocation Evolution in Sub‐10 nm Metallic Nanocrystals
Advanced Science, EarlyView.Atomic‐scale TEM imaging reveals how nanosecond electropulses drive dislocation evolution in sub‐10 nm metallic nanocrystals. Enhanced electron scattering at structural heterogeneities nucleates dislocation loops and dipoles, which then repeatedly interact and annihilate, causing dislocation density fluctuations or structural disordering.
