Determination of the volume fraction of retained austenite in a 300m steel by heat tinting technique
(2007-12-01)
Applying the Heat Tinting Technique the microestrutural characterization of a 300M steel (medium carbon steel) was accomplished. The steel was austenitized for 20 min to 900°C, followed by holding at 400°C (in the bainitic ...

Particle size effect on abrasion resistance of mottled cast iron with different retained austenite contents
(ELSEVIER SCIENCE SA, 2009)
Effects of particle abrasive sizes on wear resistance of mottled cast iron with different retained austenite contents were studied. Abrasive wear tests using a pin test on alumina paper were carried out, using abrasive ...
Retained austenite phase detected by Mössbauer spectroscopy in ASTM A335 P91 steel submitted to continuous cooling cycles
(Elsevier, 2019-04)
Samples of ASTM A335 P91 steel submitted to continuous cooling at different rates were analyzed in the form of foils and powders by means of Mössbauer spectroscopy. The Continuous Cooling Transformation (CCT) diagram of ...
Response of ferrite, bainite, martensite, and retained austenite to a fire cycle in a fire-resistant steel
(2021-12-01)
Understanding the kinetics of microstructural degradation during the event of a fire is of major relevance to future optimization of fire-resistant steels (FRS). In this work, we use in situ synchrotron X-ray diffraction ...
Tempering temperature effects on abrasive wear of mottled cast iron
(ELSEVIER SCIENCE SA, 2009)
The effects of different tempering temperatures (300-600 degrees C) on abrasive wear resistance of mottled cast iron were studied. Abrasive wear tests were carried out using the rubber-wheel test on quartz sand and the pin ...
Effect of the as-built microstructure on the martensite to austenite transformation in a 18Ni maraging steel after laser-based powder bed fusion
(2021-10-01)
During laser-based powder bed fusion, the non-equilibrium solidification conditions promote local elemental segregation, leading to a characteristic microstructure composed of cellular walls. These walls can display either ...
