Journal ArticleDOI
Influence of carbon content and microstructure on corrosion behaviour of low alloy steels in a Cl− containing environment
TL;DR: In this article, a salt fog test and an outdoor test of low-alloy steels (A and B) with different carbon content was performed by a commercial weathering steel 09CuPCrNi and showed that homogeneous microstructures, proper amounts of carbon content and fine carbon-rich phases are beneficial for the corrosion resistance of steels.
Journal ArticleDOI
Influence of prior austenite grain size on martensite–austenite constituent and toughness in the heat affected zone of 700MPa high strength linepipe steel
TL;DR: In this article, the effect of prior austenite grain size on martensite-austenite (M-A) constituent during the second pass reheating and its consequent influence on impact toughness was investigated.
Journal ArticleDOI
Influence of Martensite–Austenite constituents formed at different intercritical temperatures on toughness
TL;DR: In this article, the impact of Martensite-Austenite (M-A) constituents formed at different intercritical temperatures on toughness was elucidated by using Gleeble thermal simulation technique.
Journal ArticleDOI
Stabilization of retained austenite by the two-step intercritical heat treatment and its effect on the toughness of a low alloyed steel
TL;DR: In this article, a fine film-like stable retained austenite was obtained in a Fe 0.08C-0.5Si-2.4Mn-Ni steel by the two-step intercritical heat treatment, where the first step of intercritical annealing creates a mixed microstructure of preliminary alloy-enriched martensite and lean alloyed intercritical ferrite.
Journal ArticleDOI
Stability of retained austenite in multi-phase microstructure during austempering and its effect on the ductility of a low carbon steel
TL;DR: The work hardening behavior of retained austenite exhibited a three-stage process such that necking was delayed as mentioned in this paper, which was attributed to the multi-phase microstructure and TRIP effect.
