Influence of Hot Rolling Process on Microstructure and Properties of Low-strength IF Steel
Published 2025-02-01“…The results show that the microstructure of hot-rolled IF steels in the austenitic zone was equiaxed grains, while the grains of hot-rolled IF steel in the ferrite zone are elongated and fibrous along the rolling direction; Compared with the austenitic zone hot rolling process, the optimum process parameters for ferrite zone rolling are heating temperature 1 150 ℃+final rolling temperature 800 ℃+coiling temperature 720 ℃, in which the yield strength Rp0.2 is significantly reduced, and the size of precipitated phases is overall larger by 70-85 nm, but there is no significant difference in the size of TiN precipitated phases; In terms of texture, cold-rolled annealed IF steel γ texture is stronger, and the orientation distribution of each component in the main texture is more concentrated with smaller differences in strength.The corresponding r value increases by 0.64, while the △r value decreases by 0.35, significantly improving its deep drawing formability. …”

The effect of high-temperature intercritical annealing and rolling strain on the development of trimodal microstructure in low-carbon steel
Published 2025-01-01“…Considering the presence of ferrite grains in three different categories (coarse, fine, and ultrafine) it can be concluded that the trimodal microstructure was formed in the 50% + 550 and 75% + 550 samples, while in the 25% + 550 sample, even the bimodal microstructure was not formed. …”

Failure Analysis of Corrosion-Induced Perforation in B10 Copper-Nickel Alloy Pipelines
Published 2024-12-01“…The B10 copper-nickel alloy pipeline used for seawater transportation on a certain platform was found to have corrosion perforation at the weld joint between the elbow and the flange during a shutdown inspection.In this study, the failure mechanism of corrosion perforation was analyzed using macroscopic morphology observation,scanning electron microscopy (SEM),energy-dispersive spectroscopy (EDS),X-ray diffraction (XRD) and metallographic examination.Results showed that “sugar cube”-like intergranular corrosion morphologies were commonly observed at the bottom of corrosion pits on the flange, in erosion-wear areas, corrosion grooves, perforated regions and at the bottom of corrosion pits on the elbow.Locally, a “stepped” exfoliation morphology was observed, where grains were progressively stripped layer by layer.The preferentially corroded grain boundaries formed a circuit, and the surrounded grains were selectively denickelized and dissolved, resulting in grain spalling.The reduced hardness and coarse columnar grain structure of the flange further decreased the material’s corrosion resistance.The corrosion perforation of the copper-nickel alloy pipeline occurred in the erosion-sensitive zones and the weld heat-affected zones with the poorest corrosion resistance.This failure was the result of the synergistic effects of erosion wear, intergranular corrosion and selective dealloying.Enhanced corrosion monitoring is recommended for similar locations in service pipelines.…”
