Microstructure of Microalloyed Linepipe Steels [PDF]

open access: yesVolume 1: Codes, Standards and Regulations; Design and Constructions; Environmental; GIS/Database Development; Innovative Projects and Emerging Issues, 2000
The aim of this study was to characterize the microstructure of microalloyed linepipe steels. The steels investigated were X70 (0.04 wt% C - 0.02 wt% Ti - 0.07 wt% Nb) and X80 (0.04 wt% C - 0.025 wt% Ti - 0.09 wt% Nb) steels, where the numbers refer to their specified minimum yield strength (SMYS) in ksi.

Titanium microalloyed steels [PDF]

open access: yesIronmaking & Steelmaking, 2018
This review considers the compositions, the main process routes, microstructure and structural properties of microalloyed steels. The background and brief history are followed by sections dealing with aspects of precipitation, which control grain size and dispersion strengthening in ferrite–pearlite steels, the approaches to modelling thermomechanical ...

Static Recrystallization Behavior of Low-Carbon Nb-V-Microalloyed Forging Steel

open access: yesMetals, 2022
Static recrystallization is a method of tailoring the microstructure and mechanical properties of steels, which is important for microalloyed forging steels as the hot deformation process significantly affects their mechanical properties.

Corrosion characterization of new low manganese microalloyed X65 steels in sour and NON-SOUR synthetic seawater

open access: yesJournal of Materials Research and Technology, 2022
API 5L X65 microalloyed steels are extensively used for oil and gas transportation. In many cases, reserves of such resources contain H2S, constituting what is called a sour medium, at which hydrogen-induced failures are critical.

Effects of Grain Refinement on the Corrosion Behaviour of Microalloyed Steel in Sulphuric Acid Solutions

open access: yesInternational Journal of Electrochemical Science, 2012
Microalloyed steels have been widely used in many applications, particularly in car bodies and other engineering parts. This is because these steels are characterized by their high strength and high ductility.

Selected Problems of the Microstructure Evolution During Microalloyed Steel Wire Rod Production Process

open access: yesArchives of Metallurgy and Materials, 2017
In the present study, we have discussed the selected problems of microstructure development during the whole manufacturing process, i.e. continuous casting, thermomechanical processing, and cold metal forming of the microalloyed steels wires.

Influence of the Strain Rate on the Notch Toughness of Cold-Forming Steels

open access: yesCommunications, 2004
The paper analyses the influence of the strain rate with loading rates of 1.7.105 4.8 m.s1 on the notch toughness of hot-rolled microalloyed steels S 315 MC and S 460 MC and cold-rolled deep-drawing steels DC 06, H 220 B and H 220 P.

Resistance Rapid Heating of Aluminum Coatings in an Extreme High Vacuum–Adequate Atmosphere for Hot Stamping

open access: yesAdvanced Engineering Materials, EarlyView.
The subject of this work is the development of a corrosion‐protective coating on steel sheets for form hardening. Rapid heating in an extreme high vacuum (XHV)‐adequate atmosphere is a useful method to prevent oxidation during alloying of 22MnB5 and aluminum to obtain a metallurgical bonding.
