The hot ductility of four microalloyed steels was examined under varying cooling rates and titanium contents. Hot tensile testing and microscopic analysis revealed that ferrite formation and TiNb(CN) precipitation critically influence hot ductility. Lower cooling rates enhance ductility by increasing ferrite thickness and modifying precipitate features,

Effect of V and N on the microstructure evolution during continuous casting of steel [PDF]
Low Carbon (LC) steel is not expected to be sensitive to hot tearing and/or cracking while microalloyed steels are known for their high cracking sensitivity during continuous casting. Experience of the Direct Sheet Plant caster at Tata Steel in Ijmuiden (

This study develops a lightweight AlFeNiTiV complex concentrated alloy (density: 6.83 g cm−3) through Cu microalloying and lattice coherency tuning. The alloy exhibits ultrahigh compressive strength exceeding 3.3 GPa, 11.8% strain, and retains a yield strength of 1311.6 MPa at 600 °C, demonstrating a phase interface strategy for high‐temperature ...

Leveraging Atomic Disorder to Modulate Hydrogen Storage Thermodynamics in Intermetallics
This work introduces atomic disorder into TiFe‐based intermetallics through multi‐element substitution to tune hydrogen storage properties. A series of B2‐structured, compositionally complex intermetallics are synthesized and evaluated, revealing that increased atomic disorder enhances hydride stability.

Here, the microstructure evolution of a new generation ultrahigh‐strength S1300‐type structural steel has been investigated for direct‐quench and tempering route. Various stages of tempering are elucidated by thorough characterization, and a new strain‐size parameter of martensite is proposed to have a correlation with hardness, which will be useful in
