TL;DR: The effect of hydrogen in steels from the atomistic to the continuum scale is described by reporting theoretical evidence supported by quantum calculation and modern experimental characterisation methods, macroscopic effects that influence the mechanical properties of Steels and established damaging mechanisms for the embrittlement of steels.

TL;DR: In this article, the thermomechanical processing of high strength low allow (HSLA) steels during low-temperature roughing, followed by rapid reheating to higher temperatures was investigated to better understand the Nb dissolution kinetics in austenite, and the subsequent precipitation behavior during the final finishing passes.

TL;DR: In this article, the role of a range of elements, particularly Mo, in the interphase precipitation process was investigated, and the effect of composition on interphase precitation was investigated.

TL;DR: In this paper, a new thermomechanical processing route is described for a microalloyed steel, with roughing deformation below the recrystallisation-stop temperature (T5), followed by a rapid reheat to 1200°C for 10s, and then finish deformation at the same temperature as the rough deformation.

TL;DR: In this article, a new maraging steel, based on carbide precipitation, is described, which achieves ultra-high strength and high tensile elongation through the simulatenous precipitation of Cr and Mo-rich carbides and Mn-rich reverted austenite.
