Atomistic weak interaction criterion for the specificity of liquid metal embrittlement [PDF]

open access: yesScientific Reports, 2022
Liquid metal embrittlement (LME) occurs in some solid–liquid metal elements’ couples (e.g., Fe-Zn and Al-Ga), called specificity. Although some material parameters like solubility and bonding energy were suggested as controlling factors, none could be ...

Comparing Xe+pFIB and Ga+FIB for TEM sample preparation of Al alloys: Minimising FIB‐induced artefacts [PDF]

open access: yesJournal of Microscopy, Volume 282, Issue 2, Page 101-112, May 2021., 2021
Abstract Recently, the dual beam Xe+ plasma focused ion beam (Xe+pFIB) instrument has attracted increasing interest for site‐specific transmission electron microscopy (TEM) sample preparation for a local region of interest as it shows several potential benefits compared to conventional Ga+FIB milling.

Self‐Catalyzed Chemically Coalescing Liquid Metal Emulsions [PDF]

open access: yesAdvanced Science, Volume 12, Issue 20, May 29, 2025.
A new type of liquid metal emulsion is developed that chemically activates and becomes electrically conductive under mild thermal stimulus. The activation mechanism occurs through a unique set of catalytic dehalogenation and chemical oxide etching reactions. These emulsions are 3D printable and exhibit high shape retention after being heated.

Significance of cutting plane in liquid metal embrittlement severity quantification [PDF]

open access: yesSN Applied Sciences, 2021
The automotive industry is turning to advanced high strength steels (AHSS) to reduce vehicle weight and increase fuel efficiency. However, the zinc coating on AHSS can cause liquid metal embrittlement (LME) cracking during resistance spot welding.

Effect of Steel Composition and Processing Parameters on the Penetration Depth of Microcracks in ZnFe‐Coated Boron Steels

open access: yessteel research international, Volume 92, Issue 10, October 2021., 2021
The widely observed microcracking of ZnFe‐coated press hardening steels (e.g., 22MnB5) can be minimized with the help of the improved hardenability of steel (e.g., 22MnMoB), which enables hot forming at exceptionally low hot forming temperatures of 550 °C or below. The cracking behavior can be connected with the metal‐induced embrittlement (MIE), which

Effect of Process Parameters and Nugget Growth Rate on Liquid Metal Embrittlement (LME) Cracking in the Resistance Spot Welding of Zinc-Coated Steels

open access: yesJournal of Welding and Joining, 2022
Although the influence of weld process variables on LME cracking was known to be significant, limited studies have been conducted on the effect of process variables with systematic approaches in the equivalent nugget growth behavior and heat input. This study aimed to identify the effect of weld process variables on LME sensitivity with the equivalent ...

Bending Behavior of Zinc‐Coated Hot Stamping Steels

open access: yessteel research international, Volume 92, Issue 10, October 2021., 2021
The bending behavior of zinc‐coated martensitic steels produced via two different cooling routes, namely, with and without precooling, is investigated. Precooling leads to the formation of individual ferrite grains within the martensitic matrix in the near‐surface regions.

Towards an explanation of liquid metal embrittlement cracking in resistance spot welding of dissimilar steels

open access: yesMaterials & Design, 2020
Automotive advanced high-strength steels and ultra-high-strength steels, such as Q&P980 steel with a Zn coating, are prone to liquid metal embrittlement (LME) surface cracking during resistance spot welding, while traditional low carbon steels (LCSs) do ...

Effect of type-C liquid metal embrittlement on mechanical properties of spot-welded TRIP steel

open access: yesJournal of Materials Research and Technology, 2021
Type-C liquid metal embrittlement (LME) crack refers to an internal crack in the heat-affected zone near the notch area. In contrast to type-A and type-B LME, the type-C LME has rarely been studied for its effect on the mechanical properties of the metal.

Liquid Metal Embrittlement Susceptibility of Hot Formed Zn-Al-Mg Coated Steel with Eutectic Coating Microstructure

open access: yesMetals, 2023
Liquid metal embrittlement (LME) in Zn-based coating plates during hot stamping is an abnormal phenomenon where intimate contact between liquid Zn and a steel matrix results in the penetration of liquid Zn into the matrix, causing ruptures.
