3D mapping of orientation variation and local residual stress within individual grains of pearlitic steel using synchrotron dark field X-ray microscopy

open access: yesScripta Materialia, 2021
Assessing the local residual stress and orientation with nanometer resolution within embedded steel grains has remained challenging. Here we use an advanced synchrotron technique, dark field X-ray microscopy to map 3D lattice variations, including both ...

Influential factors on the deformability of colonies in pearlitic steel

open access: yesMaterials Characterization, 2021
The inhomogeneous strain distribution introduced by the tensile deformation of pearlitic steel was visualized using digital image correlation method, and the morphology of cementite was quantitatively evaluated.

Modelling of temperature and strain rate dependent behaviour of pearlitic steel in block braked railway wheels

open access: yesRailway Engineering Science, 2021
Block braked railway wheels are subjected to thermal and rolling contact loading. The thermal loading results in high temperatures and thermal stresses which cause slow time dependent processes such as creep, relaxation and static recovery of the wheel ...

Effect of interlamellar spacing on the elastoplastic behavior of C70 pearlitic steel: Experimental results and self-consistent modeling [PDF]

open access: yes, 2014
The effect of pearlite microstructure characteristics on strength and deformation of C70 pearlitic steel was investigated. Tensile tests under X-ray diffraction coupled with self-consistent model have been used to identify the role of interlamellar ...

SPD Deformation of Pearlitic, Bainitic and Martensitic Steels

open access: yesMATERIALS TRANSACTIONS, 2023
The deformation behavior of nearly fully pearlitic, bainitic and martensitic steels during severe plastic deformation is summarized in this paper. Despite their significantly different yield stresses and their microstructures, their hardening behavior during SPD is similar.

Fracture toughness, fatigue crack resistance and wear resistance of two railroad steels

open access: yesJournal of Materials Research and Technology, 2020
This research evaluated the microstructure and compared important mechanical properties of two steels for use in the railway sector. The main objective of the work was to verify the possibility of replacing a traditional C-Mn-Si pearlitic steel widely ...

Strain localization and delamination mechanism of cold-drawn pearlitic steel wires during torsion

open access: yes, 2021
Pearlitic steel wires are cold-drawn in order to attain high strength from the alignment of the pearlite colonies along the wire axis, as well as achieve a considerable reduction in the thickness of the ferrite lamellae.

A 4340 Steel with Superior Strength and Toughness Achieved by Heterostructure via Intercritical Quenching and Tempering

open access: yesMetals, 2023
The conventional 4340 steel was used after quenching and tempering, strengthened by the classical pearlitic structure where cementite particles are dispersed through the ferrite matrix. In the present study, a heterostructure microstructure consisting of

The Structural and Strength Changes Resulting from Modification of Heat Treatment of High Carbon Steel

open access: yesArchives of Metallurgy and Materials, 2016
Pearlitic steels containing from some 0,8 to 0,95% C belong to the group of unalloyed steels intended for cold drawing or rolling. One of the problems discussed in literature is cracking of pearlitic steel subjected to plastic working, caused by high ...

Low cycle fatigue simulation and fatigue life prediction of multilayer coated surfaces [PDF]

open access: yes, 2010
This paper focuses on the simulation of low cycle fatigue (LCF) failures in highly loaded coated surfaces subjected to mixed rolling-sliding contact in dry conditions. The development of an advanced finite element (FE) model and creation of a unique user-
