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.

Microstructure–Property Relationships in Thermomechanically Processed Medium-Mn Steels with High Al Content

Metals, 2018
Detailed studies on microstructure⁻property relationships of thermomechanically processed medium-Mn steels with various manganese contents were carried out. Microscopic techniques of different resolution (LM, SEM, TEM) and X-Ray diffraction methods

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%.

In Situ Investigation of Microstructure Evolution and Stress Generation During Low‐Pressure Carburizing and Quenching by Means of Synchrotron X‐Ray Diffraction

steel research international, EarlyView.
This study uses in situ synchrotron X‐ray diffraction at the German Electron Synchrotron to analyze low‐pressure carburizing (LPC) in steels. The findings reveal surface carbon saturation and carbide formation kinetics, and phase‐specific stress development during quenching. The results show carbide kinetics depend on steel grade and size, while stress

Microstructure Characterization of Bending Effects in 304L Stainless Steel Cladded with Low‐Alloy Steel Weld

steel research international, EarlyView.
Prebending of 304L/Q345R cladded plates significantly alters the subsequent weld thermal cycle and modifies the local interfacial microstructure. Combined electron backscatter diffraction (EBSD) and microscopy analysis demonstrates that deformation twinning, martensitic transformation, and defect initiation are concentrated at the trimaterial junction,

Stress corrosion cracking evaluation of martensitic precipitation hardening stainless steels [PDF]

The resistance of the martensitic precipitation hardening stainless steels PH13-8Mo, 15-5PH, and 17-4PH to stress corrosion cracking was investigated. Round tensile and c-ring type specimens taken from several heats of the three alloys were stressed up ...

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.

KINETICS AND CRACK GROWTH MECHANISM IN STEEL WITH FERRITE-MARTENSITIC COMPOSITE STRUCTURE

Advanced Engineering Research, 2011
Research results of the crack behavior examination in steels with the ferrite martensitic composite structure are presented. It is shown that the crack propagation rate in these steels is considerably lower than in the same steels with secondary sorbite ...

Effect of Si content on the mechanical behavior and microstructure of a 9Cr ferritic/martensitic steel

Journal of Materials Research and Technology
Si-containing ferritic/martensitic (F/M) steels are ideal candidate structural materials for the lead-cooled fast reactors on account of their good mechanical properties, corrosion resistance and irradiation resistance. In order to figure out the optimal

Variant selection in martensitic steels

, 2019
The martensitic phase transformation in steel is one of the most famous solid state transformation because of its contribution in the development of the modern industry. This transformation from a face-centered cubic (FCC) high temperature phase, called the austenite, to a metastable body-centered cubic (BCC) low temperature phase, the martensite, is ...
