Effect of lattice mismatch-induced strains on coupled diffusive and displacive phase transformations

, 2006
Materials which can undergo slow diffusive transformations as well as fast displacive transformations are studied using the phase-field method. The model captures the essential features of the time-temperature-transformation (TTT) diagrams, continuous ...

Influence of Aluminum on Microstructure and Mechanical Properties of Air‐Hardened Medium Manganese Steel

steel research international, Volume 96, Issue 7, July 2025.
This article investigates the influence of aluminum concentrations on the microstructure and mechanical properties of air‐hardening ductile steels. The reduction of the aluminum contents below 0.5 wt% is unfavorable as it does not ensure sufficient toughness.

Impact of Partitioning Temperature Parameters during the Quenching and Partitioning Process on Medium Carbon Steels with Two Different Alloying Strategies

steel research international, Volume 96, Issue 6, June 2025.
The study investigates microstructural evolution during high‐temperature partitioning in medium‐carbon, high‐silicon aluminum‐aided steels, exploring phase transformations affecting the final microstructure. Quenching and partitioning processes, with varying primary martensite fractions, reveal significant austenite stabilization at 350 °C, but ...

The Effect of Bake Hardening on Quenched and Partitioned AISI 420 Stainless Steel

steel research international, Volume 96, Issue 5, May 2025.
The effect of bake hardening (BH) on the mechanical properties of quenched and partitioned stainless steel is studied. Suitable Q&P parameters are first determined, and subsequent BH with and without prior deformation is investigated. The results indicate that standard BH2 treatment can significantly alter the mechanical properties, suggesting that BH ...

Friction stir welding of thin DH36 steel plate [PDF]

, 2013
A series of 4, 6 and 8 mm DH36 steel welds were produced using optimum conditions for friction stir welding (FSW). Comparator welds in the same thickness from the same plates were produced using a single sided single pass process submerged arc welds (SAW)

Automated Workflow for Phase‐Field Simulations: Unveiling the Impact of Heat‐Treatment Parameters on Bainitic Microstructure in Steel

Advanced Engineering Materials, Volume 27, Issue 8, April 2025.
In this study, OpenPhase software is used to simulate low‐carbon bainitic steels. The lower holding temperature sample exhibits smaller and finer grains. Grain thickness measurements of bainitic ferrite from simulations align with the experimental observations at high temperature. Bainitic steels are extensively utilized across various sectors, such as
