Intercolonial Microdamage and Cracking Micromechanisms during Wire Drawing of Pearlitic Steel. [PDF]
Materials (Basel), 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 ...

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.

Solution Strengthening and Short-Range Order in Cold-Drawn Pearlitic Steel Wires
CrystalsPearlitic steel rods are subjected to cold-drawing processes to produce pearlitic steel wires with true strains ranging from 0.81 to 2.18. Tensile tests are utilized to attain mechanical properties of cold-drawn pearlitic steel wires.

Crack tip fields and mixed mode fracture behaviour of progressively drawn pearlitic steel [PDF]
Fracture and Structural Integrity, 2015 This paper deals with the influence of the cold drawing process on the fracture behaviour of pearlitic steels. To this end, fracture tests under axial loading were performed on steel wires with different drawing degree (from a hot rolled bar to a ...

Tensile Armor Wires Submitted to Slow Strain Rate Tests in a Corrosive Environment and Cathodic Protection: a Comparison Between Two Different Microstructures [PDF]
Materials Research, 2019 Tensile armor in flexible pipes consists of two or more layers of steel wires. Damage to the outer sheath may cause ingress of seawater in the annular space and thus corrosion of the armor wires.

Ratchetting in Cold-Drawn Pearlitic Steel Wires [PDF]
Metallurgical and Materials Transactions A, 2019 The microscopic mechanisms that accommodate uniaxial ratchetting in cold-drawn pearlitic steel wires were explored. A two-stage evolution of ratchetting strain as a function of cycle numbers was observed. The initial sudden increase of plastic strain leads to a rapid decomposition of cementite, followed by a constant ratchetting strain rate with ...

Drawing-Induced Evolution of Inclusions in Cold-Drawn Pearlitic Steel
Metals, 2021 This article focuses on the analysis of the evolution of inclusions present in eutectoid pearlitic steel subjected to a real cold drawing process. To this end, wires belonging to different stages of the manufacture chain were studied, starting from an ...
