The results demonstrate that as the process progresses, the total oxygen content, nitrogen content, and the number of inclusions in the steel gradually decline. Meanwhile, the inclusions are mainly Al2O3-bearing inclusions during the RH refining process, including single Al2O3, Al2O3–TiOx and MgO–Al2O3–TiOx. Statistical analyses reveal that the interval time for adding Al and Ti has been reduced from 6 to 3 min, the quantity of Al2O3–TiOx and MgO–Al2O3–TiOx inclusions has increased. Moreover, it is found that the oxidation state of the refining slag exerts a significant impact on the number of inclusions in DC04-N steels. As the deoxygenation products, that is, Al2O3-bearing inclusions, are continuously adsorbed by the slag, the FeO and MnO contents in the refining slag gradually decrease, while the Al2O3 content and the C/A ratio gradually increase. Therefore, it is recommended to appropriately extend the time interval for adding Al and Ti and weaken the oxidation of the top slag through modification during the RH refining process, which is beneficial for achieving high-cleanliness Al-killed low-carbon steel.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"96 10","pages":"249-260"},"PeriodicalIF":2.5,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197102","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}

Microstructural analysis reveals that a high magnetic field accelerates martensite recovery, and the width of martensitic laths increased by 150% and 130% after tempering at 200 or 500 °C, respectively. This phenomenon is likely attributed to the magnetic field influence on elevating the diffusion activation energy. Dislocation motion is accelerated due to the magnetic field, leading to dislocation accumulation. The dislocation provides more nucleation sites for the carbide precipitation compared to without the magnetic field. Furthermore, a magnetic field triggers carbide precipitation, with rod-shaped transforming into spherical ones. The mechanical properties of specimens after tempering with a magnetic field are slightly higher than those of the specimens tempered without a magnetic field, which is due to the synergistic effect of the precipitation and dislocation motion. Special attention has been paid to emphasizing the medium-temperature tempering brittleness that arises from the precipitation and micro-voids along martensite lath and prior austenite grain boundaries. The mechanism of a magnetic field-induced transformation is further explored in this study, which has important theoretical and practical implications for the creation of advanced steel materials.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"96 10","pages":"124-134"},"PeriodicalIF":2.5,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196915","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 focuses on the development of innovative methodologies for minimizing energy consumption and carbon emissions during steel production, with particular emphasis on the synergistic optimization of both long- and short-flow steelmaking processes. A carbon flow model has been constructed to analyze the material and energy flows associated with long-process (BF–BOF) and short-process (electric arc furnace (EAF)) steelmaking, as well as to assess the potential for carbon reduction through industrial symbiotic technologies. The findings illustrate that in the S2 scenario, where the proportion of EAF steel is increased to 50%, carbon emissions are reduced to 1,464.12 kg tcs, representing an 18.9% decrease. This reduction is lower than that achieved by traditional long-process steelmaking; and the industrial symbiosis technologies, such as chemical production and coke oven gas hydrogen production, can facilitate an additional reduction in carbon emissions of 41.33 kg tcs. This study offers a new pathway and reference for the green transformation of the iron and steel industry.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"96 10","pages":"185-199"},"PeriodicalIF":2.5,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196896","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 the results, it is shown that for fusion-welded parts with definite geometrical dimensions, the vertical fusion welding scheme reduces the amount of slag and welding current, but the total welding time is long and the heat-affected zone is large; the horizontal scheme is the opposite. The preset rated welding current increases nonlinearly with increasing workpiece length. Increasing workpiece length decreases the average slag pool temperature uniformity and affects the slag pool flow, Lorentz force distribution, and increases the horizontal depth of fusion and depth of slag pool; increasing thickness increases the heat capacity and also affects the changes in the aforementioned physical quantities. The height during slag replenishment is related to the part length and thickness, while the recommended thickness is related to the part length, ESFW height, and slag replenishment mechanism. To avoid thermal distortion, the maximum cross-section horizontal depth of fusion should be less than 1/3 of the thickness of fusion-welded component.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"96 9","pages":"332-347"},"PeriodicalIF":2.5,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145038400","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 terms of calculation, the average strain rate of half-life is considered the main factor affecting fracture life. A life prediction equation based on ductile fatigue theory and effective stress concept is established, introducing the average strain rate of half-life as the parameter. The existing experimental datasets of 1.25Cr0.5Mo steel are used to validate the predictive ability of the model under different load conditions. The results show that all the experimental data points fall into a range within a scatter band of ±2 on life prediction. Based on the combination of scanning electron microscopy and transmission electron microscopy characterization, the fracture behavior and damage mechanism are explored. The reasons are revealed for accelerated softening and premature failure during CFI loading.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"96 10","pages":"148-159"},"PeriodicalIF":2.5,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196801","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}

Intercritical quenching and tempering treatments produced DP steels with varying martensite fractions, analyzed using optical microscope, scanning electron microscopy, and electron backscatter diffraction. In the results, it is shown that quenching at 800 °C achieves the best impact toughness (40.5 J cm−2 at −120 °C), which is attributed to the combined effects of cooperative deformation between martensite and ferrite, effective surface energy (36.1 J m−2), and the maximum plastic deformation area (871 μm2) during crack propagation.

The high density of NiAl precipitates with an average radius of 3.47 nm and a volume fraction of 0.9% is obtained after peak aging, significantly enhancing mechanical properties while minimizing magnetic performance loss. These precipitates maintain a coherent relationship with the matrix, preventing increased magnetic anisotropy.
