TL;DR: In this article, the influence of hydrogen on the mechanical properties of four multiphase high strength steels by means of tensile tests on notched samples was investigated by performing mechanical tests on both hydrogen charged and uncharged specimens at a cross-head displacement speed of 5mm/min.

TL;DR: In this paper, pure iron and a ferrite-bainite steel were charged electrochemically using various electrolytes and combinations of current density and charging time to identify the experimental conditions where blister formation occurred.

TL;DR: In this article, a transformation-induced plasticity (TRIP) steel was subjected to different degrees of cold deformation in order to correlate the changing microstructure with the thermal desorption spectroscopy peaks.

TL;DR: In this article, four high strength steels and a pure iron, as a reference material, were studied by thermal desorption spectroscopy (TDS) in order to evaluate hydrogen trapping in these materials and to correlate it to the observed response of these materials to the previously evaluated effect of hydrogen on their mechanical properties.

TL;DR: In this paper, two lab cast steels with variable carbon content were processed to generate different microstructural constituents, and the as-quenched martensite microstructure had the highest hydrogen saturation level while a significant part of this hydrogen appeared to be diffusible.
