Effect of Cooling Practice on the Mechanical Properties of Medium‐Manganese Aluminum‐Alloyed Steels after Intercritical Annealing Quench and Partition Treatment

steel research international, Volume 96, Issue 2, February 2025.
Two medium (3 wt%)‐manganese aluminum steels are subjected to three different cooling strategies after hot rolling. The steels experience intercritical annealing quench and partition treatments subsequent to hot rolling and cooling. The results show that it is possible to enhance strength and elongation by changing the thermomechanical process and heat‐

On the Strain Hardening and Tensile Properties of AISI 4140 Steel via Single‐Step Quenching and Partitioning Treatments

steel research international, Volume 96, Issue 2, February 2025.
Single‐step quenching and partitioning treatments applied on commercial AISI 4140 steel result in an ultimate tensile strength above 2000 MPa and up to 10% elongation, which represents a significant improvement compared to quenched and tempered conditions.

Effect of the morphology of the martensite-austenite phase on fracture of the weld heat affected zone in vanadium and niobium microalloyed steels [PDF]

, 2010
In multipass welding, the intercritically reheated coarse grained heat affected zone demonstrates the worst toughness in welded joint, since it contains a high-carbon martensite with some retained austenite, known as M-A phase, which is brittle and ...

Formation of Bainite in a Low‐Carbon Steel at Slow Cooling Rate – Experimental Observations and Thermodynamic Validation

steel research international, Volume 96, Issue 2, February 2025.
A low‐carbon (0.23 wt%) carbide‐free bainitic steel is successfully developed with a total alloying addition of 4.9 wt%, which is relatively lower than alloying additions reported in similar category of steels. The present findings indicate that the currently designed low‐alloy steel composition is amenable to generation of nearly carbide‐free bainitic

Analysis of acoustic emission during the melting of embedded indium particles in an aluminum matrix: a study of plastic strain accommodation during phase transformation

, 2012
Acoustic emission is used here to study melting and solidification of embedded indium particles in the size range of 0.2 to 3 um in diameter and to show that dislocation generation occurs in the aluminum matrix to accommodate a 2.5% volume change.
