Assessing Altered Coating Adhesion on Plasma‐Deoxidized Surfaces Under Oxygen‐Free Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
This study demonstrates the effectiveness of atmospheric pressure plasma pretreatment in modifying silicon and stainless steel surfaces to improve adhesion. Argon‐hydrogen plasma increases surface roughness and improves adhesion strength, whereas pure argon results in smoother surfaces and structural changes.

INFLUENCE OF ABNORMAL AUSTENITE GRAIN GRAIN GROWTH IN QUENCHED ABNT 5135 STEEL [PDF]

open access: yesTecnologia em Metalurgia, Materiais e Mineração, 2015
Grain size in the steels is a relevant aspect in quenching and tempering heat treatments. It is known that high austenitizing temperature and long time provide an increase in austenitic grain sizes.

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.

Retained Austenite: Transformation-Induced Plasticity

open access: yes, 2016
The deformation-induced phase transformation of metastable austenite to martensite is accompanied by macroscopic plastic strain and results in significant work hardening and the delayed onset of necking. Steels that exhibit such transformation-induced plasticity (TRIP) effect possess high strength–ductility ratios and improved toughness.

Effects of Temperature and Time of Isothermal Holding on Retained Austenite Stability in Medium-Mn Steels

open access: yesApplied Sciences, 2018

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Influence of Carbonitriding Process on Phase Transformation during Case Hardening, Retained Austenite and Residual Stresses [PDF]

open access: yes, 2019
The carbonitriding process is a surface hardening technique with an ultimate goal of improving surface hardness, fatigue properties and resistance to wear of highly stressed parts.

Determination of retained austenite using an x-ray texture goniometer

open access: yes, 2000
A new X-ray technique has been developed for determining the amount of retained austenite in steels with preferred orientation, such as white cast irons and deformed steels. The technique uses an X-ray texture goniometer.

The Role of Retained Austenite and Its Carbon Concentration on Elongation of Low Temperature Bainitic Steels at Different Austenitising Temperature

open access: yesMetals, 2018
The influence of austenitising temperature on the tensile properties of low temperature bainitic steel was investigated. With the increasing austenitising temperature, a significant change of elongation was found between 850 and 950 °C, which was ...

Effects of the microstructure and retained/reversed austenite on the corrosion behavior of NiCrMoV/Nb high-strength steel

open access: yesnpj Materials Degradation, 2023
A comparison of microstructure and corrosion performance has been made between NiCrMoV/Nb steel under different heat treatments in artificial seawater. The microstructures as well as the volume fraction of austenite strongly affect corrosion resistance ...
