Resistance Rapid Heating of Aluminum Coatings in an Extreme High Vacuum–Adequate Atmosphere for Hot Stamping

Advanced Engineering Materials, EarlyView.
The subject of this work is the development of a corrosion‐protective coating on steel sheets for form hardening. Rapid heating in an extreme high vacuum (XHV)‐adequate atmosphere is a useful method to prevent oxidation during alloying of 22MnB5 and aluminum to obtain a metallurgical bonding.

Effect of microalloying on the toughness of metallic glasses [PDF]

, 2012
The effect of microalloying on the toughness of Cu-Ti-based metallic glasses is explored. Minor additions of Si and Sn in glass former Cu_(47)Ti_(34)Zr_(11)Ni_8 known to improve glass-forming ability are found here to sharply decrease toughness. The drop

The influence of Widmanstätten ferrite, martensite and grain boundary carbides on the strength and impact behaviour of high Al (0.2%) and Nb containing hot rolled steels [PDF]

, 2020
The influence of Al and Nb on the strength and impact behaviour of hot rolled 0.06%C, 1.4%Mn steels has been determined after hot rolling to 15 and 30 mm thick plate.

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

steel 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 ...

Effect of microalloying on hydrogen embrittlement resistance of 125ksi grade petroleum pipe

Journal of Materials Research and Technology
In this study, the influence of incorporating equimolar proportions of vanadium, titanium, and niobium microalloying elements into C110 steel on the hydrogen embrittlement susceptibility of oil casing steel was investigated at a strength level of 125 ksi.

Exploiting Residual Elements Arising from Scrap Steel in Future Sustainable Steel Alloy Design

steel research international, EarlyView.
Herein, the effects of residual elements Cu and Sn on grain growth, recrystallization, and phase transformation in C–Mn steel are summarized, and a case study is presented on how the presence of residual elements can be exploited to reduce deliberate Nb microalloying while achieving the same grain size control and strength during thermomechanical ...

Effect of V–Ti multi-microalloying on enhancing hydrogen embrittlement resistance in hot-stamping steel

Journal of Materials Research and Technology
Hydrogen embrittlement (HE) has become a significant concern that limits the usage of ultra-high strength hot-stamping steel. In this work, the utilization of a novel approach employing V–Ti multi-microalloying has yielded substantial improvements in the

The bi-layered precipitate phase zeta in the Al-Ag alloy system

, 2017
The Al-Ag system is thought to be a well-understood model system used to study diffusional phase transformations in alloys. Here we report the existence of a new precipitate phase, zeta, in this classical system using scanning transmission electron ...
