TL;DR: In this article, the change in low-cycle fatigue (LCF) properties and deformation microstructure due to the alteration of aluminum and silicon contents was studied in relation with the tensile properties in Fe-30Mn−(6−x)Si-xAl (x=0, 1, 2, 3, 4, 5, 6") alloys, which are high-Mn austenitic TRIP/TWIP alloys.

TL;DR: In this paper, the authors give an overview of recent progress in microstructure-specific hydrogen mapping techniques, including thermal desorption spectrometry, silver decoration, the hydrogen microprint technique, secondary ion mass spectroscopy, atom probe tomography, neutron radiography, and scanning Kelvin probe.

TL;DR: In this paper, the effect of tempering on hydrogen trapping in 0.42C-0.30Ti steel was studied by means of a hardness test, hydrogen thermal desorption spectrometry and high resolution transmission electron microscopy.
