Depending on scrap quality, a non-negligible content of tramp elements such as Cu, Sn, or Ni is introduced into the steel. As their affinity to oxygen is lower than that of iron, they typically enrich at the steel/scale interface area and along grain boundaries during oxidation, which may result in quality problems. Oxidation processes are unavoidable in solid steel processing, and therefore, a deeper understanding of the occurring phenomena, such as intergranular oxidation and liquid metal infiltration of grain boundaries, is essential to continuously improve the product quality. In this study, oxidation experiments for slab reheating were performed by simultaneous thermal analysis under near-process conditions. For a clear statement on the role of tramp elements during oxidation, steel grades with and without tramp elements were investigated. The addition of the expected future contents of Cu and Sn does not affect external oxidation, but at the interface the presence of Cu and Sn leads to the formation of liquid Cu phases and infiltration of grain boundaries. The additional presence of Ni counteracts this formation, but due to its huge impact on iron activity it favors the formation of a rough steel/scale interface. In contrast with Ni, Cu and Sn hardly have any influence on iron activity. Numerical calculations based on a diffusion model and results of the well-known thermochemical software FactSage confirm these effects.</div>","PeriodicalId":724,"journal":{"name":"Oxidation of Metals","volume":"102 2","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11085-025-10329-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heat treatments consisted of holding IN718 at 1050 °C for 2 h in a combined thermogravimetric balance and gas chromatography-mass spectrometer (GCMS). Furnace atmospheres explored included 22–703 ppm O2 and H2O concentrations of 23–387 ppm. The GCMS measurements were able to quantify the O2 and H2O concentrations during heat treatment and revealed that oxidation became measurable at approximately 800 °C. The oxidation rate was parabolic during the 1050 °C isotherm, increasing linearly with an increase in either O2 or H2O concentration up to a value of 480 ppm. Beyond 480 ppm the oxidation remained constant and equivalent to that reported in air. A two layer surface oxide structure consisting of Cr2O3 and TiNbO4 formed when the O2, and H2O content increased beyond 33 and 23 ppm respectively. Dry O2 conditions (i.e. H2O of approximately 25 ppm), caused spalling of the Cr2O3 oxide surface during cooling when the O2 ppm was 124 ppm or above. In higher H2O concentrations the Cr2O3 layer showed good adherence to the base metal and no cracking during cooling.

Two new platinum-based high-temperature alloys, Pt-10Rh-0.5Zr and Pt-10Rh-0.5Zr-0.2Y, were designed and prepared in this study. The research focuses on the high-temperature oxidation behavior of the alloys in air and the influence of oxidation on the room temperature mechanical properties of the alloys. The results show that the relationship between oxidation weight loss and temperature of these two platinum-based alloys conforms to the Arrhenius equation within the temperature range of 1400–1600 ℃, and the oxidation resistance of Pt-10Rh-0.5Zr-0.2Y alloy is better than that of Pt-10Rh.0.5Zr alloy. Examination of the surface and fracture morphology of these oxidized platinum-based alloys revealed that zirconium and yttrium oxide particles, such as ZrO2 and Y2O3, with different morphologies and structures were formed. The study also found that adding a small amount of zirconium and yttrium can significantly improve the room temperature ultimate tensile strength of Pt-10Rh alloy. However, after 20 h of high-temperature oxidation treatment at 1400 and 1500 °C, the tensile strength and plasticity at room temperature of both alloys showed a significant downward trend. Especially, the room temperature plasticity of Pt-10Rh-0.5Zr-0.2Y alloy decreased by more than 80% and exhibited a brittle fracture mode.

Nevertheless, oxidation is unavoidable for GNS metal materials utilized at high temperatures, potentially impacting the microstructure stability. In this study, we reveal the correlation between the high-temperature selective oxidation and the thermal stability of GNS layer through experiments and phase-field simulations. The improved oxidation resistance of GNS samples was ascribed to the excellent thermal stability of (Cr, Mn)3O4 oxides and a large proportion of low-energy twin boundaries. After prolonged oxidation, the GNS layer exhibited a bimodal microstructure. To analyze the elemental diffusion mechanism and microstructure evolution in the GNS layer, the phase-field simulation technique was employed. Selective oxidation led to the concentration of chromium reduced in the grain-boundary region, thereby diminishing the thermal stability of the grains and causing abnormal grain growth in the surface layer. Particularly, grain growth had a cumulative effect, the topmost grains coarsening will cause grain growth in the underlying layers, and subsequently, the grains in the interior region will also be gradually affected.</div>","PeriodicalId":724,"journal":{"name":"Oxidation of Metals","volume":"102 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994337","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}

Wüstite plays an important role in the oxide layer of these steels used for hot working. However, understanding its transformation behavior during cooling is crucial for controlling the final oxide layer structure. Slow cooling rates have a significant influence on the final wüstite content, resulting in inaccurate representations of the composition of the oxide layer at temperatures above 570 °C. The aim of this study was to determine the influence of cooling rate on the wüstite content in the oxide layer after high temperature oxidation. It was found that for hot-worked steel samples oxidized at 700 °C or higher, a cooling rate of more than 1000 °C min−1 is required to suppress the eutectoid transformation and maintain the realistic wüstite content. At lower temperatures (570 °C–600 °C), a cooling rate of more than 100 °C min−1 is required to achieve the wüstite content observed at oxidation temperatures in the oxide layer.
