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 ...

Hybrid micro-macromechanical modelling of anisotropy evolution in pearlitic steel
, 2012 Large shearing and/or stretching of pearlitic steel leads to a re-orientation and alignment of cementite lamellas on the microscopic level. In this paper a macroscopic model formulated for large strains is proposed for pearlitic steel that captures this ...

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.

Simulation of high pressure torsion tests of pearlitic steel
, 2014 High pressure torsion (HPT) is a severe plastic deformation (SPD) method that can transform the characteristic lamellar microstructure of pearlitic steel to a severely deformed and aligned microstructure with respect to the deformation direction.

On the modeling of deformation induced anisotropy of pearlitic steel
, 2010 A micromechanically based plasticity model for modeling of anisotropy in pearlitic steel is investigated. The model was proposed in Johansson and Ekh~[1] and takes into account large strains as well as deformation induced anisotropy.

Materials and Corrosion, Volume 76, Issue 10, Page 1478-1496, October 2025.This study investigated the effect of subcritical heat treatment and cold work on the hydrogen embrittlement (HE) susceptibility of the X65 D pipeline steel. Hydrogen charging reduced the ductility of all specimens. Both subcritical annealing and cold working decreased somewhat the degree of HE.

Very High Cycle Fatigue Performance of Ductile Cast Iron With Different Microstructures
Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 9, Page 3950-3966, September 2025.ABSTRACT The very high cycle fatigue performance of four ductile cast irons, a solid solution strengthened ferritic, ferritic‐pearlitic, and two austempered ductile cast irons, was investigated by ultrasonic fatigue testing under fully reversed loading conditions. The step‐stress fatigue testing method incorporating re‐use of runouts was employed, with
