Hydrothermal‐Assisted In Situ Intercalation Synthesis of Ti3C2Tx MXene in 6 Hours

open access: yesSmall Methods, EarlyView.
This work presents a rapid, scalable strategy for synthesizing Ti3C2Tx MXene through hydrothermal‐assisted etching with in situ intercalation, achieving complete synthesis and delamination within 6 h at 90°C. The process accelerates aluminum removal, promotes efficient delamination, and enables direct exfoliation under mild conditions, producing high ...

Alloy Qualification for Producing Quench and Tempered Plate Steels with Extra‐Heavy Gage

open access: yessteel research international, EarlyView.
This study develops alloy concepts for ultraheavy steel plates (>100 mm) with ≥690 MPa yield strength. Through dilatometry and Jominy testing, the effects of Mo, Ni, and B on hardenability are quantified. A synergy between 0.5% Mo and 0.5%–1.0% Ni ensures core strength at low cooling rates, while boron microalloying suppresses ferrite and promotes ...
