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 ...

Texture inheritance of cold drawn pearlite steel wires after austenitization

Materials Science and Engineering: A, 2014
Abstract 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.

Microstructure and strengthening mechanisms in cold-drawn pearlitic steel wire

Acta Materialia, 2011
Abstract 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 ...

Pearlitic steel wire: High carbon steel based natural nanomaterial by lead patenting process

Materials Today: Proceedings, 2016
The 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.

Effect of interlamellar spacing on cementite dissolution during wire drawing of pearlitic steel wires

Scripta Materialia, 2000
Cold drawing is an effective process to increase the strength of fully pearlitic steels with an acceptable level of ductility. Microstructural changes and deformation behavior of the pearlite during wire drawing are closely related to the initial microstructure of the pearlite.

Analysis of the Plasticity Characteristics of Progressively Drawn Pearlitic Steel Wires

Materials Science, 2016
The changes in the plasticity characteristics of prestressing steel wires in air and in hydrogenating environments caused by the process of cold drawing are investigated on the basis of slow strain-rate tests on smooth specimens. The tested pearlitic steel is highly susceptible to hydrogen embrittlement in all stages of cold drawing.

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.

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.

Comment on “Cementite decomposition in heavily drawn pearlite steel wire”

Scripta Materialia, 2002
Abstract A comment on the experimental data that give evidence for decomposition of cementite in pearlitic steels due to cold work is presented based on the recent and previous studies. Data obtained by using X-ray diffraction, Mossbauer spectroscopy, APFIM and relevant conclusions are discussed.
