Influence of niobium microalloying on the thermal stability of medium-carbon carbide-free bainitic steel

Journal of Materials Research and Technology, 2021
This paper investigates the influence of niobium on the thermal stability of ultra-fine bainite microstructures and their mechanical properties by means of an isothermal transformation at 340 °C, followed by tempering in the range of 200–700 °C for two ...

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%.

Effect of Double Annealing on the Microstructure and Mechanical Properties of a Medium Manganese Steel

steel research international, EarlyView.
A double intercritical annealing strategy is proposed to tailor the multiphase microstructure and mechanical response of a medium‐Mn steel. The treatment produces an ultrafine mixture of ferrite, martensite and multiple austenite populations with graded thermal and mechanical stability, formed through austenite reversion and controlled retransformation.

Grain and phase stress criteria for behaviour and cleavage in duplex and bainitic steels [PDF]

, 2006
Stress analyses by X-ray diffraction are performed on a cast duplex (32% ferrite) stainless steel elbow and a bainitic (95% ferrite) pressure vessel steel. During an in situ tensile test, micrographic observations are made (visible glides and microcracks)

Accelerated Fatigue Testing of High‐Speed Steel

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The staircase method is commonly employed in the characterization of metals to determine their fatigue limit. In this approach, the stress amplitude is systematically varied around the assumed fatigue limit in consecutive tests. However, its applicability for in‐process optimization in alloy design and development is limited by the large ...

New insights for preformed martensite of carbide-free bainitic steels austempered below Ms temperature: Inconsistent effects of microstructure, stability of retained austenite, and mechanical properties

Journal of Materials Research and Technology
Previous studies have shown that the effect of preformed martensite (PM) on bainitic steel is complex. In this study, the austempering process for medium-carbon carbide-free bainitic steel was conducted in a salt bath environment at various temperatures ...

Cyclic Plastic Material Behavior of Novel Austenitic (C + N) Steel Additively Manufactured by PBF‐LB/M

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 4, Page 1313-1326, April 2026.
ABSTRACT The newly introduced high manganese high strength (C + N) steel Printdur HSA was developed for the additive manufacturing process PBF‐LB/M. It consists of a fully austenitic grain structure. This study aims to evaluate the cyclic plastic material behavior of this (C + N) steel.

On the Impact Energy Absorption of an Advanced High‐Strength Bilayer Steel Composite Consisting of Carbide‐Free Bainitic Steel and High‐Mn Twinning‐Induced Plasticity Steel

Advanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
Excellent combinations of strength and impact toughness are obtained in a bilayer composite of high‐strength carbide‐free bainitic (CFB) steel and high‐ductility twinning‐induced plasticity (TWIP) steel. The composite absorbs energy at small strains when the notch is placed on the TWIP side and at high strains when the notch is placed on the CFB side ...

Stress Corrosion Tests for Prestressing Steels—Part 2: Susceptibility of Quenched and Tempered Wires—Influence of Chromium

Materials and Corrosion, Volume 77, Issue 1, Page 36-45, January 2026.
Cr‐alloyed quenched and tempered prestressing steel wires were found to be as highly susceptible as non‐Cr‐alloyed ones. This finding is in contrast to the known literature. A newly developed and reproducible method for assessing susceptibility to hydrogen‐induced stress corrosion cracking was used.
