Fabrication of nanostructured pearlite steel wires using electropulsing [PDF]
Materials Science and Technology, 2018 This work reports the refinement of pearlite structure into nanostructure using electropulsing. Nanostructured pearlitic steel wires possess nanoscale lamellae or nanoscale grain microstructures. Fabrication of nanostructures by severe plastic deformation and lamellar to grain transformation have been investigated.

Intercolonial Microdamage and Cracking Micromechanisms during Wire Drawing of Pearlitic Steel
Materials, 2023 This paper studies the drawing-induced intercolonial microdamage (ICMD) in pearlitic microstructures. The analysis was performed from the direct observation of the microstructure of the progressively cold-drawn pearlitic steel wires associated with the distinct steps (cold-drawing passes) of a real cold-drawing manufacturing scheme, constituted by ...

Soft Magnetic Properties of Ultra-Strong and Nanocrystalline Pearlitic Wires
Nanomaterials, 2021 The paper describes the capability of magnetic softening of a coarse-grained bulk material by a severe deformation technique. Connecting the microstructure with magnetic properties, the coercive field decreases dramatically for grains smaller than the ...

Cold-drawn pearlitic steel wires
Progress in Materials Science, 2016 Abstract Cold-drawn pearlitic steel wires have attracted considerable interest because of their excellent combination of strength and ductility. The physical interpretation of these properties has been a subject of repeated controversial discussions in the literature.

Influence of surface defects on the fatigue crack initiation in pearlitic steel
MATEC Web of Conferences, 2014 Tensile fatigue tests were performed under load control, with constant stress range Δσ on pearlitic steel wires, from the hot rolled bar to the commercial prestressing steel wire (which has undergone seven cold drawing steps).
