Investigation of the mechanical work during ultrasonic fatigue loading using pulsed time‐resolved X‐ray diffraction

Journal of Synchrotron Radiation, Volume 31, Issue 1, Page 17-27, January 2024.
The development of a time‐resolved X‐ray diffraction technique using synchrotron radiation in pulsed mode to estimate the stress and the mechanical work during an ultrasonic fatigue test is presented.In the energy production and transportation industries, numerous metallic structures may be subjected to at least several billions of cycles, i.e.

Strain-induced coarsening of ferrite lamella in cold drawn pearlitic steel wire

, 2020
Strain-induced coarsening of ferrite lamellae in pearlitic steel wires during cold drawing was investigated. Experimental results demonstrated that the coarsening of ferrite lamellae was caused by strain-induced grain boundary migration.

Molecular Dynamics Analysis of Hydrogen Diffusion Behavior in Alpha-Fe Bi-Crystal Under Bending Deformation

Applied Mechanics
The hydrogen embrittlement (HE) phenomenon occurring in drawn pearlitic steel wires sometimes results in dangerous delayed fracture and has been an important issue for a long time.

Strength Anisotropy and Residual Stress in Drawn Pearlite Steel Wire

ISIJ International, 2004
Strength anisotropy is found by tensile and compressive tests for a drawn pearlite steel wire, where the compressive tests are performed for prepared specimens along directions of 0, 45 and 90 degrees with respect to the drawing direction. The influence of annealing on such anisotropic strength is also examined. To make clear the origin of the strength

Drawing Behavior of Pearlitic Steel Wire Rods Controlled by Boron Addition in Medium Carbon Steel

ISIJ International, 2002
One of the most effective methods to increase the productivity and cost down in wire manufacturing is eliminating the patenting heat treatment during drawing process. For that purpose, the ductility increase of wire rods is essential to draw wire without breakage.

Structural Parameters and Strengthening Mechanisms in Cold-Drawn Pearlitic Steel Wires [PDF]

, 2012
Pearlitic steel wires have a nanoscale structure and a strength which can reach 5 GPa. In order to investigate strengthening mechanisms, structural parameters including interlamellar spacing, dislocation density and cementite decomposition, have been ...

Exploring high strength metallic materials: a lesson from pearlitic steel wire

, 2019
In human history, the development of stronger materials through the ages is reflected with names of eras illustrating our progress. Besides phase transformations, plastic deformation is one of the major methods to produce products with reliable and ...

Fatigue cracking in high-strength cold-drawn pearlitic steel wires for anchorage in rocks [PDF]

, 2016
This paper analyzes the fatigue crack path in two pearlitic steels with very different microstructural arrangement: a hot rolled pearlitic steel bar and a commercial high-strength cold drawn prestressing steel wire frequently used for anchorage in rocks.

Modeling of Anisotropy Evolution in Pearlitic Steel

, 2013
In a pearlitic structure, large deformations lead to a re-orientation and alignment of cementite lamellae on the microscopic level. These changes in the microstructure of pearlitic steel under large plastic deformations inducesubstantial degrees of ...

Hierarchical Structure and Strengthening Mechanisms in Pearlitic Steel Wire

, 2017
Microstructure evolution and strengthening mechanisms have been analyzed in a cold-drawn pearlitic steel wire (the strongest engineering materials in the world) with a nanostructure down to 10 nm and a flow stress up to 5.4 GPa. The interlamellar spacing and the cementite lamellae thickness are reduced during drawing in accordance with the change in ...
