Void initiation and microstructural changes during wire drawing of pearlitic steels
Materials Science and Engineering: A, 1995Microstructural changes and void initiation in fully pearlitic steels during cold wire drawing were investigated by performing tensile tests and microstructural examination with scanning electron microscopy. In this investigation, the primary focus was on cementite lamellae aligned transversely to the drawing axis in pearlite colonies.

Microstructure and texture evolution in fully pearlitic steel during wire drawing
Science China Technological Sciences, 2013The evolution of morphology of pearlite and crystallographic texture of ferrite matrix in fully pearlitic steels during wire drawing were quantitatively investigated. The study revealed that a fiber structure of the pearlite morphology and a fiber texture of the ferrite matrix begin to take shape and develop gradually with increasing strain.

Dislocation density and configuration in fully pearlitic steel during wire drawing
Materials Research Innovations, 2014This study explores the dislocation density and configuration in fully pearlitic steel wires during the cold wire drawing process by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The XRD results show that the dislocation density increases from 1·1×1014 m−2 to 1·4×1015 m−2, with the drawing strain increasing from 0 to 1·65 ...

Macro- and Micromechanics of Pearlitic-Steel Deformation in Multistage Wire Production
Steel in Translation, 2018Ninefold drawing of pearlitic steel wire is investigated. On the basis of multiscale computer models, the behavior of pearlite colonies at the surface of the wire and in its central layer is analyzed. The key factors are the orientation of the cementite lamellae relative to the drawing axis, the interlamellae distance, and the shape of the cementite ...

Hydrogen effects in multiaxial fracture of cold-drawn pearlitic steel wires
Engineering Fracture Mechanics, 2017Abstract Heavily drawn pearlitic steel wires have a markedly oriented microstructure as a consequence of the manufacturing process by cold drawing, thereby becoming anisotropic materials in the matter of fatigue and fracture behaviour. Such a micro-arrangement influences hydrogen assisted fracture (HAF) and produces multiaxial fracture in the form of

Cementite Dissolution in Cold Drawn Pearlitic Steel Wires: Role of Dislocations
Materials Science Forum, 2013Despite numerous investigations in the past, mechanism of cementite dissolution has still remained a matter of debate. The present work investigates cementite dissolution during cold wire drawing of pearlitic steel (~ 0.8wt% carbon) at medium drawing strain (up to true strain 1.4) and the role of dislocations in the ferrite matrix on the dissolution ...
