Hierarchical structures in cold-drawn pearlitic steel wire [PDF]
Acta Materialia, 2013 Abstract The microstructure and crystallography of drawn pearlitic steel wires have been quantified by a number of electron microscopy techniques including scanning electron microscopy, transmission electron microscopy, electron backscatter diffraction and nanobeam diffraction, with focus on the change in the structure and crystallography when a ...

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 ...

Fabrication of nanostructured pearlite steel wires using electropulsing [PDF]
Materials Science and Technology, 2017 This work reports the refinement of pearlite structure into nanostructure using electropulsing. Nanostructured pearlitic steel wires possess nanoscale lamellae or nanoscale grain microstructures.

Hirarchical structures and strength in cold-drawn pearlitic steel wire [PDF]
, 2014 Deformation, as one of the major methods to improve the (specific) strength of metals, can be combined with phase transformation to improve the strength of nanometals to an ultrahigh level close to the theoretical strength in single crystals. This is demonstrated by the analysis of the microstructural evolution, strengthening mechanisms and strength ...

Hierarchical Structure and Strengthening Mechanisms in Pearlitic Steel Wire [PDF]
, 2017 Microstructure evolution and strengthening mechanisms have been analyzed in a cold-drawn pearlitic steel wire (the strongest engineering materials in the world) with a nanostructure down to 10 nm and a flow stress up to 5.4 GPa. The interlamellar spacing and the cementite lamellae thickness are reduced during drawing in accordance with the change in ...

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 ...

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 ...

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.
