X-ray computed laminography: A brief review of mechanisms, reconstruction, applications and perspectives Open

Wenjia Du, Francesco Iacoviello, Mateen Mirza, Shangwei Zhou, Junfu Bu , et al. · 2025

In situ Construction of Free-Standing High-Performance Ni-Based Dual Intermetallic Composites for Alkaline Hydrogen Evolution Open

Xu Wang, Quan Li, Shikang Feng, Yanru Liu, Caixia Xu , et al. · 2025

Alkaline electrolytic hydrogen production has emerged as one of the most practical methods for industrial-scale hydrogen production. However, the initial hydrolysis dissociation in alkaline media impedes the hydrogen evolution reaction (HE…

Revealing hot tear formation dynamics in Al–Cu alloys with X-ray radiography Open

Insung Han, Shikang Feng, Fabian Wilde, Patrick S. Grant, Enzo Liotti · 2023

Hot tears can arise during the late part of alloy solidification because of the shrinkage of isolated liquid as it turns to solid and may have a catastrophic effect on cast tensile properties. Although there are correlations to suggest all…

The mechanism of Fe-rich intermetallic compound formation and growth on inoculants revealed by electron backscattered diffraction and X-ray imaging Open

Shikang Feng, Zelong Jin, Wenjia Du, Insung Han, Andrew Lui , et al. · 2023

Fe-rich intermetallics affect critically the mechanical properties and recyclability of aluminium alloys. Increasing effort has been spent on the inoculation of these intermetallics, hoping to promote a finer distribution. Recently Al-5Ti-…

Tracking the evolution of hot tears in aluminium alloys using high-speed X-ray imaging Open

Insung Han, Shikang Feng, Andrew Lui, Fabian Wilde, Patrick S. Grant , et al. · 2023

Hot tears are detrimental defects forming during the final stage of solidification when the remaining liquid loses the capacity to compensate for liquid to solid volume shrinkage. Although a mature semi-quantitative description of hot tear…

Investigating Metal Solidification with X-ray Imaging Open

Shikang Feng, Insung Han, Andrew Lui, Robin Vincent, Gideon Ring , et al. · 2022

In the last two decades, X-ray imaging techniques have been used increasingly to study metal solidification in real-time as, thanks to advances in X-ray sources (synchrotron and laboratory-based) and detector technology, images can now be …

X-ray Imaging of Alloy Solidification: Crystal Formation, Growth, Instability and Defects Open

Shikang Feng, Enzo Liotti, Patrick S. Grant · 2022

Synchrotron and laboratory-based X-ray imaging techniques have been increasingly used for in situ investigations of alloy solidification and other metal processes. Several reviews have been published in recent years that have focused on th…

Nucleation bursts of primary intermetallic crystals in a liquid Al alloy studied using in situ synchrotron X-ray radiography Open

Shikang Feng, Enzo Liotti, Andrew Lui, Matthew D. Wilson, Patrick S. Grant · 2021

In-situ X-ray radiography of twinned crystal growth of primary Al13Fe4 Open

Shikang Feng, Ying Cui, Enzo Liotti, Andrew Lui, C.M. Gourlay , et al. · 2020

Real-time synchrotron X-ray radiography of nucleation, growth and phase selection of FE-rich intermetallic compounds in Al alloy solidification Open

Shikang Feng · 2019

In-situ synchrotron X-ray radiography has been used to study the\ndynamics of nucleation, growth and other temperature related phe-\nnomena of Fe-rich and analogous faceted IMCs. Measurements from\nradiographs have been combined with post-…
