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 & Engineering A: Structural Materials: Properties, Microstructure and Processing, 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 ...

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 ...

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 ...

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 ...

Cementite decomposition in heavily drawn pearlite steel wire
Scripta Materialia, 2001Heavily 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.

Effect of interlamellar spacing on the delamination of pearlitic steel wires
Scripta Materialia, 1996Abstract 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, 2007The 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, 2015AbstractEffects 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.
