Effect of Spheroidizing and Normalizing Treatments on the Electromagnetic Behavior and Microstructural Transformations of Ferritic-Pearlitic Steel Wire for Flexible Marine Pipelines [PDF]
The tensile armor of flexible marine pipelines, responsible for the flow of oil and gas, is composed of the helical arrangement of steel wires subjected to complex stress modes that can cause unpredictable failures.

Assessing the Very High Cycle Fatigue Behavior and Frequency Effect of Structural Steel Welds
ABSTRACT The very high cycle fatigue behavior of S275J2+N flux‐core arc welded joints was investigated using the ultrasonic fatigue testing method at a loading frequency of 20 kHz. A bespoke specimen design featuring the weld toe was employed to more suitably represent in‐service welded joints than typical ultrasonic fatigue testing specimens.

Comparative Fatigue Analysis of Structural Steels Considering Welding and Surface Effects
ABSTRACT There are limited data on the very high‐cycle fatigue for structural steel welds for over 10 million cycles. The purpose of this research is a fatigue performance comparison of the welds made of steels S355JR+AR and S275JR+AR. The goal of reaching the gigacycle fatigue domain is achieved using the ultrasonic fatigue testing at 20 kHz.

A robust computational framework is proposed, which is designed to simulate microstructural‐scale plastic deformation and damage in pearlitic steels. The framework is calibrated and validated using experimental data from pearlitic steel rail samples. Subsequently, it is employed to investigate the impact of microstructural parameters, such as cementite

Effect of Ce on inclusions and carbides in M2 high-speed steel
Two heats of M2 high-speed steel with different rare-earth (Ce) contents were produced by a domestic steel plant using the following process route: electric arc furnace (EAF) smelting → ladle furnace (LF) refining → vacuum degassing (VD) → electroslag ...

Taking advantage of co‐deformation mechanisms is a promising way to achieve fine grain metal matrix composites or architectured structures with unique properties. Understanding physical mechanisms is critical to promote refinement or fragmentation or mechanical mixing.

Multi‐principal‐element alloys (MPEAs) with high work hardening capacity, like Hadfield steel, can extend conventional alloy systems. In this study, CoFeNi‐based MPEAs with Mn and C are cast and mechanically finished using ultrasonic milling. The resulting MPEAs show significant hardness increase and improved wear resistance, demonstrating their ...

Influence of Tramp Elements on Surface Properties of Liquid Medium‐Carbon Steels
Greenhouse gas restrictions are forcing steel producers to increase recycling rates. The resulting higher tramp element content affects the oxidic cleanness. Herein, the influence of tramp elements on surface tension, contact angle, and formation of nonmetallic inclusions is investigated.

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