Four principal mechanisms—solid solution strengthening, grain boundary strengthening, dislocation strengthening, and precipitation strengthening—are systematically evaluated using advanced microstructural characterization techniques. The results showed that grain boundary strengthening is relatively insensitive to tempering temperature, while dislocation and solid solution strengthening are notably enhanced at lower tempering temperatures due to sluggish recovery and the retention of solute carbon, respectively. Although precipitation strengthening did not make a significant contribution, it strongly influences solid solution strengthening by modulating the solute carbon concentration. Accounting for the effect of solute carbon substantially improves the correlation between calculated and experimental yield strengths. This study highlights the interplay between precipitation hardening and solid solution strengthening in determining the mechanical properties of martensitic steels, providing valuable guidance for alloy design and heat treatment optimization.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"97 4","pages":"1856-1865"},"PeriodicalIF":2.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147683054","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 systematically investigates the effects of magnesium on secondary phases, elemental segregation, and hardness in H13 steel using optical microscopy, scanning electron microscopy, energy-dispersive spectroscopy, electron probe microanalysis, and micro-Vickers hardness testing. Key findings demonstrate that magnesium modifies inclusions by transforming Al2O3–CaO–SiO2 complex inclusions into discrete AlMgO4 (spinel) and MgO particles. This modification significantly increases the population of inclusions smaller than 3 μm while virtually eliminating inclusions larger than 8 μm, concurrently reducing chained inclusion clusters. The steel exhibits banded microstructures parallel to the rolling direction, characterized by alternating bright and dark bands. Elemental mapping confirms pronounced segregation of C, Mo, and Cr within dark bands, where V-rich primary MC-type carbides preferentially form. Magnesium addition refines these dark bands, yielding a more uniform distribution while simultaneously reducing the quantity and size of primary carbides. Crucially, magnesium enhances both the magnitude and uniformity of matrix microhardness. These improvements stem from Mg's ability to mitigate elemental segregation, thereby optimizing carbide distribution and ultimately elevating the steel's hardness and service performance.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"97 4","pages":"1866-1876"},"PeriodicalIF":2.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147683523","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 results show that in steel, the main inclusions are large, elongated MnS particles, which are prone to plastic deformation during hot working. When the Te content in the steel reaches 0.016%, the original inclusions are transformed into MnTe–MnS composite inclusions with smaller sizes and morphologies approaching spherical or ellipsoidal shapes. These composite inclusions exhibit excellent morphological stability during high-temperature deformation. First-principles calculation results indicate that MnTe has a relatively high bulk modulus but lower shear modulus, Young's modulus, and hardness, exhibiting characteristics of ductility. 2D lattice disregistry analysis further indicates that MnTe matches MnS better than either phase matches the Fe matrix, and MnTe also shows superior lattice compatibility with Fe. Consequently, MnTe is more likely to nucleate on MnS surfaces, forming stable MnTe–MnS that alleviate stress concentration at the inclusion–matrix interface and enhance interfacial bonding stability. These findings provide a theoretical basis for regulating sulfide inclusion morphology in steel and for optimizing its microstructure and mechanical properties.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"97 4","pages":"2012-2022"},"PeriodicalIF":2.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147683573","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}

There has been a core challenge to achieve the low superheat and constant temperature casting due to significant temperature fluctuation under multi-ladle teeming. In the current study, a mathematical model coupling the electromagnetic field, flow field, temperature field, and inclusion transport is established for an IH tundish. The influence of IH power is investigated, and a dynamic IH power control method is proposed. The results show that IH significantly alters the flow pattern, inducing a downward steel stream in the discharging chamber due to eccentric electromagnetic force. IH can also achieve temperature compensation; the superheat can be controlled to within ±2 K under the condition of dynamic IH power. The relationship between the variation of temperature and IH power is linear after the mean residence time is reached. Additionally, IH enhances the removal rate of inclusions, reaching up to 86.48% under the dynamic IH condition.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"97 3","pages":"1323-1333"},"PeriodicalIF":2.5,"publicationDate":"2026-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147570341","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}

B2O3 forms 2D-BO3 and 3D-BO4 units, decreasing the network stability of silicate slags. Furthermore, B2O3 forms low-melting compounds with CaO and MgO, thereby reducing the melting temperature and viscosity of slags. B2O3 as a replacement for bentonite in the pellets reduces the pelletization process's specific energy consumption and the slag rate in the blast furnace ironmaking process. B2O3 acts as a fluxing agent, boron microalloying agent, inclusion modifier, and slag stabilizer in steelmaking processes. B2O3 can replace hazardous CaF2 in iron and steelmaking processes and reduce the environmental impact. B2O3-based mold fluxes exhibit a shear-thinning property and are less reactive. The valorization potential of B2O3-modified slags improves due to induced glass-forming ability and stable phase formation. Eventually, the future scope of studying the effect of B2O3 additions in iron and steelmaking slags and the challenges associated with industrial scalability is discussed. This detailed review reveals that B2O3 addition at different stages of the iron and steelmaking process creates a pathway for a sustainable future.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"97 3","pages":"1279-1310"},"PeriodicalIF":2.5,"publicationDate":"2026-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147568624","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 objective of this study is to examine the LP-DED processability window for the rail repair alloy E11018-G. The E11018-G powder, produced via gas atomization, is characterized and deposited onto C45 steel substrates. Following the optimization of LP-DED process parameters, the investigation is extended to evaluate external factors influencing porosity, including powder porosity, powder moisture, ambient humidity, and the application of laser remelting. The results present the processability window for E11018-G and identify powder porosity, originating from the gas atomization process, as the primary contributor to porosity in the LP-DED deposits. By systematically adjusting process parameters and external factors, internal porosity in LP-DED specimens is reduced from 0.7% to 0.04%. Microstructural analysis of the additively manufactured material reveals a predominantly fine-grain ferritic structure with an average hardness of 235–250 HV0.3.
