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 ...

Machinability of Multiphase Microalloyed Steel

open access: yesProcedia CIRP, 2012
Abstract The machining of multiphase (ferrite-bainite-martensite) microalloyed steel was carried out in a high speed lathe to assess the machinability. The mechanical properties of multiphase (ferrite-bainite-martensite) microalloyed steel were analogous to those of quenched & tempered steels.

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

open access: yessteel 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 Annealing on Structure and Fatigue Properties of Microalloyed Steel

open access: yesCommunications, 2006
Advanced microalloyed steels (HSLA steels) contain microstructural components whose mechanical properties can be altered by exposure to elevated temperatures, for example, in application of welding cycles.

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

open access: yessteel 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

open access: yessteel 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.

Revealing the corrosion resistance mechanism of ultrahigh-strength titanium microalloyed weathering steel

open access: yesJournal of Materials Research and Technology
This study used cyclic immersion tests and electrochemical techniques, along with various characterization methods, to compare the corrosion resistance of 2.2Cr and 3Cr titanium microalloyed weathering steels and investigate the corrosion resistance ...

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

open access: yessteel 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%.

Reducing the use of Fossil Carbon and Fuels to Defossilize the Electric Steelmaking Route: Evaluation of the Effects of Alternative C‐Bearing Materials and Hydrogen in the Electric Arc Furnace

open access: yessteel research international, EarlyView.
The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

Development of Microalloyed Intragranular Ferrite Steel With High Strength and Toughness

open access: yesTeshugang, 2005
The general chemical compositions of microalloyed intragranular ferrite steels are 0.2~0.4C,0.2~0.8Si, 1.0~1.7Mn,0.05~0. 15V. It is a main measure to increase the strength and toughness of ferite-pearlite microalloyed steel using recrystallized forging ...
