Electrical properties and microstructure fractal analysis of magnesium-modified aluminium-silicate ceramics [PDF]

, 2011
The addition of Mg2(NO)3 and some active additives, composed of Al salts, to the mixtures of kaolinite and bentonite can provide clay compositions which, after sintering at high temperatures, produce very porous ceramics with microcrystalline and ...

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 ...

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 ...

INFLUENCE OF Ti MICROALLOYING ON ZAMAK-5

Journal of Scientific Reports-A, 2023
ZAMAK-5 is a Zn-Al alloy which contains 3.9-4.3 % Al, 0.75-1.25 % Cu and 0.03-0.06 % Mg. Low melting temperature and good castability are some of the advantages of ZAMAK-5. In the present study, the composition of ZAMAK-5 alloy was modified by microalloying it with Ti.

Bath Vibration During Open Eye Formation in a Physical Model of a Steelmaking Ladle

steel research international, EarlyView.
Using a physical model, this study shows that vibration measurements reliably predict open eye size in steelmaking ladles, offering a practical alternative to visual monitoring. Vessel vibrations stabilize faster than the open eye, except at high frequencies near the bottom.

Phase Transformation Behavior of Continuously Cooled Fe–C–V–(Mo) Alloys

steel research international, EarlyView.
Additions of vanadium and molybdenum microalloying are shown to reshape phase transformations in clean low‐carbon steels. By tracking microstructural shifts during continuous cooling, the work uncovers the correlation between transformation kinetics, ferrite morphology, and hardness.

Grain Size Evolution and Mechanical Properties of Nb, V–Nb, and Ti–Nb Boron Type S1100QL Steels

Metals, 2021
Titanium additions are often used for boron factor and primary austenite grain size control in boron high- and ultra-high-strength alloys. Due to the risk of formation of coarse TiN during solidification the addition of titanium is limited in respect to ...

Zr and Hf microalloying in an Al-Y-Fe amorphous alloy. Relation between local structure and glass-forming ability [PDF]

, 2008
International audienceThe effects of the addition of small amounts of Zr and Hf (0.5 - 3 %) on the atomic structure of Al88Y7Fe5 metallic glass were examined from extended x-ray absorption fine structure (EXAFS) experiments to better understand the ...

Press Hardening for Sustainable Lightweight Chassis Design in Heavy‐Duty Vehicles: A Material Performance and Life Cycle Assessment Approach

steel research international, EarlyView.
The article explores how high‐strength steels and press hardening revolutionize lightweight chassis design for heavy‐duty vehicles. It reveals that press hardened steels combined with shot peening can cut weight by up to 34% and reduce environmental impact by 21%–32%.
