Evolution of cementite morphology in pearlitic steel wire during wet wire drawing
Materials Characterization, 2010The 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.

Deformation of cementite in cold drawn pearlitic steel wire
Materials Science and Engineering: A, 2014Abstract 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 ...

Microstructure and strengthening mechanisms in cold-drawn pearlitic steel wire
Acta Materialia, 2011Abstract Strengthening mechanisms and strength–structure relationships have been analyzed in a cold-drawn pearlitic steel with a structural scale in the nanometer range and a flow stress of about 3.5 GPa. The wires have been drawn up to a strain of 3.7 and the structures analyzed and quantified by transmission electron microscopy and high resolution ...

Hardening and softening mechanisms of pearlitic steel wire under torsion
Materials & Design, 2014Abstract The mechanical behaviors and microstructure evolution of pearlitic steel wires under monotonic shear deformation have been investigated by a torsion test and a number of electron microscopy techniques including scanning electron microscopy (SEM) and transmission electron microscopy (TEM), with an aim to reveal the softening and hardening ...

Pearlitic steel wire: High carbon steel based natural nanomaterial by lead patenting process
Materials Today: Proceedings, 2016The high strength springs are made from fully pearlitic hypereutectoid steel wires. This fully pearlitic structure in hypereutectoid steel wires are obtained by a special heat treatment process called lead patenting process. This pearlitic structure in steel wires is the best example of natural nanomaterials.

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 ...

Materials Science Forum, 2021
Cold drawn wires were produced by drawing the pearlitic wire rod (5.5 mm diameter). Cold drawing involved multiple stages to a final drawing strain of ≈ 2.5. The cold drawing alters the pearlite morphology. During the wire drawing, the change in morphology is location dependent. This will create the gradient in stain and strain mode between the surface

Analysis of Pearlitic Cold Drawn Steel Wire
Materials Science Forum, 2015The effect of microstructure on the mechanical properties of cord steel wires was investigated. Material properties and damage behaviours were identified. Metal cord, for reinforcing articles of an elastomeric material, such as tires, conveyor belts and so on of the single strand type, in particular made up of a plurality of 3, 4 or 6 wires, where in ...
