Linking Heat Treatment to Plastic Deformation in Pearlitic Steels Through Mesoscale Modeling

Advanced Engineering Materials, Volume 27, Issue 21, November 2025.
Surface wear on rail and wheel steels results from surface deformation during use. This research uses mathematical models to forecast the plastic behavior of pearlitic steels, connected to the microstructure formed during heat treatment. While the cooling rate impacts the steels’ strength, the size of prior austenite grains and blocks does not ...

Microstructural Evolution, Performance, and Triboelectric Response of Cu–Fe Composites Processed via Deformation‐Driven Metallurgy

Engineering Reports, Volume 7, Issue 10, October 2025.
Microhardness reached a maximum of 158.5 ± 3.9 HV at 4 wt.% Fe, with tensile strength peaking at 331.9 ± 9.9 MPa, whereas higher Fe addition (6 wt.%) caused microhardness and tensile strength to decline to 142.4 ± 4.8 HV and 294.7 ± 9.2 MPa, respectively, due to particle clustering and thermal softening.

Assessing the Very High Cycle Fatigue Behavior and Frequency Effect of Structural Steel Welds

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 4, Page 1529-1541, April 2025.
ABSTRACT The very high cycle fatigue behavior of S275J2+N flux‐core arc welded joints was investigated using the ultrasonic fatigue testing method at a loading frequency of 20 kHz. A bespoke specimen design featuring the weld toe was employed to more suitably represent in‐service welded joints than typical ultrasonic fatigue testing specimens.

Synchrotron Diffraction Study of the Cementite Phase in Cold Drawn Pearlitic Steel Wires [PDF]

Materials Science Forum, 2013
Energy dispersive synchrotron diffraction has been carried out on cold drawn pearlitic steel wires. In this paper the observed cementite peaks are analysed. For a broad range of true drawing strains sin²(Ψ) curves have been measured. The residual stress in the cementite is found to saturate after reaching a maximum at a strain of about 1.6.

Influence of back tension on wire deformation heterogeneity and texture intensity: A coupled macro-micro calculation study

Journal of Materials Research and Technology
Pearlitic steel wires are typically produced through cold drawing process, where the wire is pulled through drawing dies by external forces, leading to diameter reduction and length elongation.

Comparative Fatigue Analysis of Structural Steels Considering Welding and Surface Effects

Strain, Volume 61, Issue 2, April 2025.
ABSTRACT There are limited data on the very high‐cycle fatigue for structural steel welds for over 10 million cycles. The purpose of this research is a fatigue performance comparison of the welds made of steels S355JR+AR and S275JR+AR. The goal of reaching the gigacycle fatigue domain is achieved using the ultrasonic fatigue testing at 20 kHz.

An Experimental and Computational Framework to Investigate the Microstructural Effects on the Mechanical Properties of Pearlitic Steels

Advanced Engineering Materials, Volume 27, Issue 2, January 2025.
A robust computational framework is proposed, which is designed to simulate microstructural‐scale plastic deformation and damage in pearlitic steels. The framework is calibrated and validated using experimental data from pearlitic steel rail samples. Subsequently, it is employed to investigate the impact of microstructural parameters, such as cementite
