Influence of Cooling Rates and Titanium Content on Hot Ductility in Niobium‐Fixed Microalloyed Steels

steel research international, Volume 97, Issue 2, Page 719-730, February 2026.
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,

Atomic‐Level Structural Characteristics of β‐Relaxation in Metallic Glasses

Advanced Science, Volume 13, Issue 5, 27 January 2026.
Using in situ synchrotron radiation X‐ray techniques, this study experimentally characterizes β‐relaxation at the atomic scale, linking it explicitly to tricapped trigonal prism (TTP)‐like atomic structures and fast atomic motions. Cyclic heating reveals β‐relaxation as irreversible yet reactivatable through rejuvenation, offering unprecedented insight

Machinability of Multiphase Microalloyed Steel

Procedia 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.

Effect of Ti and TiNb Microalloying on Microstructures and Mechanical Properties of 2200 MPa Low-Alloy Ultra-High-Strength Steels

Metals
The 2200 MPa low-alloy ultra-high-strength steels microalloyed with Ti (Ti-steel) and Ti and Nb (TiNb-steel) were quenched at 860 °C and tempered at 180 °C, and the mechanical properties, microstructure, and precipitated phase were studied by SEM, TEM ...

Evaluation of the Corrosion Resistance of Heat Resistant Cast Alloys in Ammonia Containing Atmospheres: The Role of Oxide Scales

Materials and Corrosion, Volume 77, Issue 1, Page 97-111, January 2026.
Application of centrifugally cast alloys during Ammonia Cracking in ammonia containing atmospheres at high temperatures (up to 900°C) induces corrosion by means of nitridation. The mechanisms of material degradation are not reliably understood yet. This article focuses on the identification of corrosion mechanisms for Cr‐Ni‐Fe‐ and Cr‐Ni‐Fe‐Al cast ...

Microstructure Development in a New Generation S1300‐Type Ultrahigh‐Strength Structural Steel on Tempering

steel research international, Volume 97, Issue 1, Page 524-542, January 2026.
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

Influence of boron content on the fracture toughness and fatigue crack propagation kinetics of bainitic steels [PDF]

, 2016
The relatively good combination of high strength and ductility makes bainitic steels a candidate to replace many other steels in industrial applications. However, in service, ductility and strength are not up to standard requirements.

Metamodeling of Void Closure during Hot Flat Rolling

steel research international, Volume 97, Issue 1, Page 104-115, January 2026.
This work aims to present a fast metamodel for void closure during hot flat rolling. The model takes into account every individual void of void distributions as found in industrial material and is capable of calculating the resulting void closure within only few seconds of computational time without loosing significant accuracy compared to expensive ...

Modification of Eutectic Al–Si Alloy With Trace Ti and Zr for Automotive Applications in Improved Electrochemical Corrosion Performance

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Titanium and zirconium are crucial grain refiner elements that significantly influence the characteristics of the Al–Si automotive alloy. Here, three different alloys are prepared: the eutectic Al–Si alloy with traces of 0.1% Ti and 0.1% Zr.
