However, solidification defects limit the industrial production of MMnS as it belongs to the peritectic class of alloys. Considering recent progress, it mandates a comprehensive review of the role of solidification behavior and various processing routes on microstructure–property correlation. Hence, the present article addresses microstructure evolution during solidification, TMP, HT, and corresponding mechanical properties. Quenching & partitioning (Q&P) and intercritical annealing (IA) are considered for the present review. It is observed that δ-ferrite transforms to austenite by a massive transformation mechanism after the peritectic reaction. High strength but low elongation is found in Q&P as compared to IA MMnS. Further, the occurrence of discontinuous yielding is associated with both HT routes. However, it is preventable with process parameters. Ni addition generally enhances the strength–ductility balance in comparison with Ni-free MMnS. However, it primarily depends on microstructural characteristics such as phase fraction, distribution, morphology, degree of recrystallization, precipitates, and retained austenite stability. Thus, optimum processing routes can be designed considering the aforementioned factors.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"96 9","pages":"26-47"},"PeriodicalIF":2.5,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145037792","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 indicate that MnS mainly appears as aggregated small-sized spherical shapes (type I MnS) in the chill zone of the bloom, while in columnar zone, it tends to form strip-like or irregular morphologies (type II MnS), and no type III MnS is observed. The size of MnS increases from the surface to the center of the samples, with the maximum equivalent diameter increasing from 1.2 to 6.0 μm. A model, considering the effects of solute redistribution and cooling rate, is established to calculate the precipitation and growth of MnS in continuous casting bloom, which is achieved by coupling theoretical calculations with the discrete solidification units. The calculated results demonstrate that sulfur segregation is the controlling factor for the precipitation and growth of MnS, which are well consistent with experiments. This work suggests that enhancing the cooling rate in the secondary cooling zone or improving homogenization of this new low-carbon alloy steel bloom can effectively reduce the growth rate of MnS and mitigate the formation of type II MnS.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"96 9","pages":"408-419"},"PeriodicalIF":2.5,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145038552","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}

However, thermodynamic experiments overestimate CO2 conversion because the temperature drop in the process is not taken into account. Therefore, FactSage is employed to reevaluate it. Calculations are validated by comparison with experiments. It is found that employing CO2 for the slag splashing process leads to a decrease in equilibrium temperature. Increasing the carbon addition enhances CO generation and CO2 conversion but results in a further reduced temperature. Elevating the temperatures of the slag and CO2 has no effect on CO generation and CO2 conversion. However, it proves beneficial for increasing the equilibrium temperature. As the most effective measure, increasing the FeO content in the slag improves CO2 conversion while significantly lowering the slag solid fraction. When the initial FeO content is 17.24 mass%, the initial temperature is 1873 K, and the CO2 temperature is 300 K, the optimal carbon addition is 1.5 mass%.

A wear map and damage mechanism map for M42 HSS containing rare earth have been established. Based on the magnitude of wear rates, the wear map can be divided into three regions: mild wear, medium wear, and severe wear. As contact stress and sliding velocity increase, the damage mechanism evolves through three stages: initial slight scratching with fewer microvoids from the detachment of small-sized carbides, followed by increased scratching with more microvoids, and culminating in severe oxidation characterized by extensive microvoids due to the fracture and detachment of larger carbides. Carbide spalling in various sizes emerges as a key factor contributing to microstructural damage and the deterioration of wear performance in M42 HSS. A quantitative correlation between carbide spalling and wear rate has been established, identifying critical thresholds of carbide spalling proportions that indicate the transition from mild to severe wear.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"96 9","pages":"299-309"},"PeriodicalIF":2.5,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145038225","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 investigates the macro/semimacro segregation and mechanical properties of bloom and rod for CF53 camshaft steel. Based on the findings, the study proposes a mechanism and strategy for controlling the macroscopic and semimacroscopic homogeneity of CF53 camshaft through soft reduction. The results indicate that applying a 7–10 mm reduction when the center solid fraction is 0.1–1.0 can promote the flow of liquid steel at the solidification end, reduce the size of the equiaxed crystals, significantly decrease the central segregation and the carbon range on transverse cross sections, and considerably reduce the size and number and solutes enrichment of semimacroscopic spot segregations in the blooms. Correspondingly, the central segregation and banded defects in the rods improve. The plasticity and toughness in the radial direction of the rods are enhanced. This demonstrates that SR can synergistically regulate the macro/semimacro homogeneity of camshaft steel blooms and rods, providing high-quality materials for subsequent processing and improving the competitiveness of camshaft products.","PeriodicalId":21929,"journal":{"name":"steel research international","volume":"96 9","pages":"284-298"},"PeriodicalIF":2.5,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145038224","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}
