TL;DR: In this paper, the continuous cooling transformation (CCT) behaviors of three low carbon pipeline steels containing the different carbon and alloy additions such as Mn, Nb, V, Ti and/or Mo were investigated in the undeformed and deformed conditions, respectively.

TL;DR: In this paper, the micro-fracture mechanisms of an UFAF pipeline steel are investigated by in situ tensile testing in a transmission electron microscope, and the results indicate that a grain-boundary-film structure composed of martensite/austenite could significantly influence the crack propagating behavior in the UfaF steel, consequently lowering the fatigue-crack growth rate by enhancing roughness-induced crack closure during cyclic loading.

TL;DR: In this article, the hot deformation behavior as well as its effect on the phase transformation of the clean acicular ferrite pipeline steel with simple chemical composition has been investigated and the optimum TMCP parameters were designed.

TL;DR: In this article, a low-carbon Mn-Mo-Nb pipeline steel designed for acicular ferrite microstructure was investigated and three independent TTT curves for isothermal phase transformation, namely, polygonal ferrite-pearlite transformation, massive ferrite transformation and bainitic transformation, respectively.

TL;DR: In this article, the performance of both acicular ferrite and ultrafine ferrite in H2S environments was evaluated and the results showed that the two microstructures have the optimum HIC resistance as well as the good mechanical properties.
