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.

Microstructure–Property Relationship in Cold-Drawn Pearlitic Steel Wires
Metallurgical and Materials Transactions A, 2020The 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; (

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.

Deformation bands in fully pearlitic steel during wire drawing
Science China Technological Sciences, 2014The deformation of fully pearlitic steels during wire drawing has been investigated for both longitudinal section and transverse section by back-scattered electron imaging (BSEI), electron back-scattered diffraction (EBSD), and transmission electron microscope (TEM).

Cementite dissolution in heavily cold drawn pearlitic steel wires
Acta Materialia, 1997The influence of cold wire drawing on the structure of a pearlitic steel containing 0.7 wt% of carbon and subjected to a strain of approximately 3.5 has been studied. The as-deformed microstructure is very fine, with an interlamellar spacing close to 20 nm, and contains high internal elastic strains.

Computer Simulation of Micro-Mechanic in Pearlitic Steel Wire Drawing
Materials Science Forum, 2020Cold-drawn high-carbon steel wire with pearlite microstructure is one of the most popular raw materials for modern reinforcing ropes. Lamellae thinning, changes in interlamellar interface and metallographic texture, strain localization is the main property-forming phenomena in the wire drawing process. However, the experimental study of these phenomena

Microstructure evolution in pearlitic steels during wire drawing
Acta Materialia, 2002Abstract 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

Fragmentation of as-drawn pearlitic steel wires during torsion tests
Engineering Fracture Mechanics, 1998Abstract During free end torsion tests of cold drawn eutectoid steel wire, primary fracture frequently causes further fragmentation of the wire. The size and orientation distribution of the pre-existing microcracks at the moment of the primary fracture, and the unloading stress waves determine the secondary fracturing behaviour.

Mechanical and Thermal Stability of Heavily Drawn Pearlitic Steel Wire
MRS Proceedings, 1996AbstractHaving 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 ...

Texture inheritance of cold drawn pearlite steel wires after austenitization
Materials Science and Engineering: A, 2014Abstract In this paper, microstructure and mechanical properties of cold drawn pearlitic steel wires were investigated by combining SEM and XRD analysis with tensile testing. Experimental results show that the tensile strength of wires increases from 1250 MPa to 3280 MPa with increasing drawing strain of 3.2.
