Effect of interlamellar spacing on the delamination of pearlitic steel wires

Scripta Materialia, 1996
Abstract The increased interlamellar spacing causes the larger sized globular cementite particles in colonies initially aligned transverse to the drawing axis, and results in the occurrence of more frequent and larger sized void formation during drawing.

Strain Aging of Heavily Drawn Pearlitic Steel Wires

Advanced Materials Research, 2007
The strain aging of heavily drawn pearlitic steel wires has been studied by means of electrical resistivity mearsurement. The kinetic of the early stage of strain aging after being drawn to true strain 2.89 is described by a Johnson-Mehl equation. The apparent activation energy ΔH is estimated as 31.7kJ/mol.

Effect of vanadium on microstructure and property of pearlitic steel wire

Materials Research Innovations, 2015
AbstractEffects of vanadium micro-alloying on the microstructure and material properties of pearlitic steel were investigated, in an effort to obtain higher strength wire with good thermal stability. Experimental results showed that V element mainly existed in cementite and acted to strengthen cementite within pearlitic wire.

Cementite decomposition in heavily drawn pearlite steel wire

Scripta Materialia, 2001
Heavily drawn pearlitic wires have been investigated extensively over the years for its unusual strainhardening behavior as well as for the high strength with acceptable level of ductility. They are widely used for tire cord, springs, wire rope, and suspension bridge cable.

Deformation of cementite in cold drawn pearlitic steel wire

Materials Science and Engineering: A, 2014
Abstract Nanostructural evolution of cementite lamellae in pearlitic steel wires subjected to cold drawing remains elusive, making it difficult to understand the origin of remarkable ductility in cementite. Using high-resolution transmission electron microscopy (HRTEM), the mechanisms underlying the inelastic deformation of cementite in pearlitic ...

Evolution of cementite morphology in pearlitic steel wire during wet wire drawing

Materials Characterization, 2010
The evolution of the cementite phase during wet wire drawing of a pearlitic steel wire has been followed as a function of strain. Particular attention has been given to a quantitative characterization of changes in the alignment and in the dimensions of the cementite phase.

Microstructure–Property Relationship in Cold-Drawn Pearlitic Steel Wires

Metallurgical and Materials Transactions A, 2020
The difficulty in predicting flow stress of a cold-drawn pearlitic steel wire arises from the complex microstructural transformations induced by cold drawing. For assessing properly the different contributions to strengthening, four quantities must first be expressed as a function of strain $$ \varepsilon $$: (i) residual volume fraction of cementite; (

Microstructure evolution in pearlitic steels during wire drawing

Acta Materialia, 2002
Abstract Major processes affecting microstructure of a drawn pearlitic wire including lamellae thinning, changes in inter-lamellar interface and metallographic and crystallographic texture, plastic flow localization, and dynamic strain aging were characterized. Heavily drawn pearlite represents a nano-composite with thickness of ferrite and cementite

Macro- and Micromechanics of Pearlitic-Steel Deformation in Multistage Wire Production

Steel in Translation, 2018
Ninefold 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 ...

Mechanical and Thermal Stability of Heavily Drawn Pearlitic Steel Wire

MRS Proceedings, 1996
AbstractHaving interlamellar spacings on the nanometer scale, there is no doubt about considering heavily drawn pearlitic steel wire as a nano-layered material. This extremely fine structure is of great technical importance: indeed, as the interlamellar distance determines the onset of plastic flow, the wire can be brought to a tensile strength beyond ...
