To address this challenge, this study explores the potential of utilizing CO2 as an oxidizing agent in stainless steel smelting, with a specific focus on its impact on decarburization and chromium (Cr) preservation. This research uncovers key insights through a comprehensive approach, combining theoretical analysis and experimental validation. Notably, CO2 injection demonstrates the potential to significantly enhance decarburization rates by ≈19–30%, offering promising prospects for improved stainless steel production efficiency and reduced carbon emissions. Moreover, the study reveals the influence of initial carbon (C) content on decarburization kinetics and the beneficial effect of CO2 injection in preserving Cr, which can contribute to maintaining the quality and cost-effectiveness of stainless steel production. While temperature variations exhibit limited impacts on reaction rates, precise temperature control remains essential for optimizing stainless steel smelting processes. This research sheds light on the promising benefits of CO2 injection in stainless steel smelting, supporting the development of sustainable and low-carbon production methods.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"96 10","pages":"489-499"},"PeriodicalIF":2.5,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work systematically investigates the effect of cooling rate and sulfur content on the inclusion formation and microstructure in X70 pipeline steels using laboratory experiments, thermodynamic calculations, and density functional theory (DFT) computations. The results show that the typical inclusions are MgAl2O4 and MgAl2O4MnS inclusions. The size of inclusions increases significantly with the increase of S contents at lower cooling rates. With the increase of S contents, MgAl2O4 inclusions can be fully wrapped by MnS inclusions. Both MgAl2O4 and MgAl2O4-MnS inclusions can induce intragranular acicular ferrite (AF). When the S content increases, the content of AF decreases sharply. Slowing the cooling rate makes the AF wider and gradually causes it to lose the AF characteristics. DFT calculations show that more oxygen vacancies are conducive to the precipitation of MnS on oxides. The small-sized inclusions are conducive to the precipitation of MnS on the oxide surface because small-sized inclusions have more oxygen vacancies. This research provides a better understanding of the factors influencing core-shell type inclusion precipitation and microstructure evolution in X70 pipeline steel.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"96 10","pages":"534-549"},"PeriodicalIF":2.5,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines ε-Cu precipitation mechanism and phase modulation in 9Cr MFS with varying Cu concentrations of 0.5, 1.0, and 1.5 wt% during aging at 650 °C. The results indicate that solute Cu atoms hardly contribute to solid solution hardening, whereas the precipitation of nano scale ε-Cu particles could contribute to aging hardness. As Cu content increases, the austenite transformation temperature A1 decreases, coinciding with the tempering temperature range designed to acquire hierarchical tempered martensitic lath structures with desirable toughness. Numerical simulations reveal that significant element partitioning takes place between austenite (γ) and ferrite (α) during the tempering process when the Cu content exceeds 1 wt%, promoting the heterogeneous nucleation of ε-Cu particles and formation of ferrite. Moreover, the ferrite phase is subjected to rapid static recovery softening during subsequent aging processes, which negate the strengthening effect of nano-sized ε-Cu precipitates. This study provides insights into the potential of Cu alloying strategies for improving the performance of martensite ferritic steels.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"96 10","pages":"526-533"},"PeriodicalIF":2.5,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings indicate that regulating the Ti/Al content ratio in steel may facilitate the formation of dominant TiOx core inclusions rather than dominant Al2O3, thereby influencing the calcium treatment's effectiveness on inclusion modification. Via reheating, the compositions of Ti2O3–MgO–Al2O3 core inclusions in high Ti/Al content ratio (5.50) steel change to Ti2O3–MgO, while (Mn, Ca) S shell with wrapped distribution become MnS and CaO–Al2O3 with short-arc, mosaic distribution due to their Ostwald aging. This implies that Al and O ions in core inclusions diffuse to surface layer, reacting with the decomposed Ca of CaS, forming more stable CaO–Al2O3. However, Al2O3–MgO–CaO core inclusions and MnS shell compositions in steel with low Ti/Al content ratio (0.50) remain almost unchanged during heating. Furthermore, the MnS and CaO–Al2O3 shell precipitates with multiple points in steel with high Ti/Al content ratio are more conducive to acicular ferrites nucleation with more branches, which are attributed to the joint action of the Mn-depleted mechanism, minimum mismatch mechanism and strain-induced mechanism, yielding a higher toughness than that at low Ti/Al content ratio.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"96 10","pages":"550-563"},"PeriodicalIF":2.5,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, the topic of material hybridization through AM is addressed, which allows for the optimization of the properties of the base materials. While AM often generates finer grain structures, particularly in SS, which enhances corrosion resistance, it can also lead to undesirable phases, precipitates, or defects like porosity that degrade performance.

As a result, it is widely used in surface engineering applications, where stringent surface quality requirements are often imposed. Oxidation throughout the production process of austenitic stainless steel strips (reheating, hot rolling, coiling, and annealing) is influenced by the interaction of alloy elements and various process parameters. The structure of the oxide layer and the chromium-depleted layer determines the surface quality after pickling.

However, the impact of microstructure on the fatigue properties of these steels remains incompletely understood. In this study, 800 MPa-grade automotive beam steel is developed by tweaking its chemical composition and lowering the coiling temperature to achieve distinct microstructural features. The new steel exhibits higher dislocation density and lower precipitation density within ferrite grains compared to conventional steels. Fatigue tests show that surface cracking is the primary failure mode for both steels. Despite similar tensile strengths, the new steel demonstrates enhanced fatigue properties, attributed to slower crack growth and improved fracture toughness, facilitated by a higher proportion of low-angle grain boundaries and increased dislocation density.
