High Strength Steels Fracture Toughness Variation by the Media [PDF]

, 2010
The stress corrosion cracking process is at this moment an unknown mechanism of deterioration. It is a process that implies the joint action of the media, the presence of corrosion or a surface defect and of stress in the metal.

Behaviour of steel prestressing wires under extreme conditions of strain rate and temperature [PDF]

, 2011
The purpose of this paper is to provide information on the behaviour of steel prestressing wires under likely conditions that could be expected during a fire or impact loads. Four loadings were investigated: a) the influence of strain rate – from 10–3 to

13C isotopic labeling to decipher the iron corrosion mechanisms in a carbonated anoxic environment

Materials and Corrosion, Volume 75, Issue 6, Page 786-795, June 2024.
The corrosion progression in a carbonate solution at 120°C was studied, using 13C labeling on a pre‐existing FeCO3‐based corrosion layer of 10‐µm thickness. Experiments showed a localized progression on an already 15‐day‐old sample. The new 13C‐labeled corrosion product was still siderite, detected only in local advances at the corrosion product layer ...

Hardening of Cylindrical Bars with Water Impinging Jet Quenching Technique

steel research international, Volume 95, Issue 6, June 2024.
Four 70 mm cylindrical steel bars are martensite hardened with different water jet flow rates using impinging jet quenching technique. A finite element method (FEM) quenching model is created to simulate phase transformations and predict the resulting microstructure, hardness, and residual stresses.

Investigation of the mechanical work during ultrasonic fatigue loading using pulsed time‐resolved X‐ray diffraction

Journal of Synchrotron Radiation, Volume 31, Issue 1, Page 17-27, January 2024.
The development of a time‐resolved X‐ray diffraction technique using synchrotron radiation in pulsed mode to estimate the stress and the mechanical work during an ultrasonic fatigue test is presented.In the energy production and transportation industries, numerous metallic structures may be subjected to at least several billions of cycles, i.e.

Influence of back tension on wire deformation heterogeneity and texture intensity: A coupled macro-micro calculation study

Journal of Materials Research and Technology
Pearlitic steel wires are typically produced through cold drawing process, where the wire is pulled through drawing dies by external forces, leading to diameter reduction and length elongation.

Особливості руйнування попередньо напруженої арматури за наводнювання у модельному робочому середовищі [PDF]

, 2015
Pecularities of fracture behaviour of progressively drawn pearlitic steels from the initial hot rolled bar (not cold drawn at all) to the final commercial product (prestressing steel wire) were investigated in air and under hydrogenation in the model ...

Fuzzy Adaptive PID Algorithm in Temperature Control System of Lead Patenting Furnace

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
In order to enhance the accuracy of temperature control of the patenting furnace, a new temperature control system (TCS) based on the fuzzy adaptive (FA)–proportion integral differential (PID) control algorithm is proposed. The system takes temperature error value and error rate as input and automatically adjusts the PID control parameter value ...

Molecular Dynamics Analysis of Hydrogen Diffusion Behavior in Alpha-Fe Bi-Crystal Under Bending Deformation

Applied Mechanics
The hydrogen embrittlement (HE) phenomenon occurring in drawn pearlitic steel wires sometimes results in dangerous delayed fracture and has been an important issue for a long time.
