Special Issue Information

Dear Colleagues,

Metals is launching a new Special Issue entitled “High Temperature Corrosion or Oxidation of Metals and Alloys (2nd Edition)”. The Special Issue will provide a platform for presenting the latest experimental and theoretical results in this innovative field. The research is not limited to the results from the laboratory and can also include the evaluation of the experimental results of metals or alloys that have been produced in large quantities. The Special Issue covers the formation of oxidation or corrosion phases, phase transformation behavior, mechanism models and numerical analyses. We especially appreciate innovative studies on overcoming the oxidation or corrosion mechanism models and prediction with value or image data in industrial production.

I would be delighted if you would be willing to contribute an original or review article to this Special Issue.

Dr. Guangming Cao
Guest Editor

The development of high-entropy alloys (HEAs) for high-temperature applications has been driven by the limitation of nickel-based superalloys in achieving optimal efficiency at higher temperatures for higher efficiency in power generation engines. The alloys must have high oxidation resistance and microstructural stability at high temperatures. Relatively equimolar multi elements involved in HEAs produce microstructure containing a single solid solution or multiphase that improves the mechanical properties and oxidation resistance resulting from sluggish diffusion and core effects. In this study, the oxidation behavior and microstructural changes of Al0.75CoCrFeNi HEA at 900, 1000, and 1100 °C in air atmosphere were investigated. Based on the XRD and SEM-EDS analysis, the mechanism of oxide scale formation and microstructural changes of the substrate are proposed. The results show that the oxidation behavior of the alloy follows a logarithmic rate law. Different oxide compounds of CoO, NiO, Cr2O3, and CrO3, θ-Al2O3, α-Al2O3, and Ni(Cr,Al)2O4 with semicontinuous oxides of Al2O3 with Cr2O3 subscale and an oxide mixture consisting of spinel of Ni(Cr,Al)2O4 and Co(Cr,Al)2O4 were found. During oxidation, Widmanstätten of FCC-A1 and BCC-B2/A2 phases in the substrate have changed. Spheroidization of B2 and a reduction in volume fraction decrease the hardness of the substrates.

Shape-memory Mn-rich austenitic stainless steels have a low high-temperature oxidation resistance because Mn tends to inhibit the formation of protective oxides. Mn depletion from oxidation also creates a ferritic Mn-depleted layer. A Mn-depleted layer formed via vacuum annealing has been associated with increased oxidation resistance. Thus, in the present study, a Mn-depleted layer was created with a pre-oxidation treatment conducted at 1000 °C for 30 min. Then, pre-treated and untreated samples were oxidized at 800 °C for up to 200 h. The resulting oxide layers were analyzed, as well as the metal/oxide interface roughness and the ferritic layer thickness. After pre-treatment, a 9 μm thick ferritic layer as well as an oxide layer richer in Cr-containing oxides than those usually observed in FeMnSiCrNi alloys oxidized at 800 °C were detected. After 200 h at 800 °C, the metal/oxide interface roughness of pre-treated samples was considerably lower. The oxidation rate of pre-treated samples was one order of magnitude lower for the first 50 h, but the effect significantly decreased afterward. The pre-existing ferritic layer was unable to stop Mn-rich oxides from being incorporated into the oxide layer, making its effect short-lived. Full article

Platinum-clad nickel composite wires with platinum layer thicknesses of 5 μm and 8 μm were prepared by a cladding drawing process. Oxidation experiments were performed using a muffle furnace at temperatures of 500 °C, 600 °C, 700 °C, and 800 °C for 1 h, 2 h, and 3 h. The oxidized samples were examined for high-temperature oxidation behavior using scanning electron microscopy (SEM) with an energy-dispersive X-ray (EDX) spectrometer attached. The results showed that the interface bond between the platinum cladding and the nickel core wire was serrated and that the thickness of the platinum cladding was not uniform. At low temperatures (500 °C and 600 °C), the diffusion rate of the nickel was low. The composite wire could be used for a short time below 600 °C. When the temperature reached 700 °C and above, the nickel diffused to the surface of the composite wire and was selectively oxidized to form a nickel oxide layer. The research results provide a theoretical reference for the selection of a service temperature for platinum-clad nickel composite wires used as the lead material for thin-film platinum resistance temperature sensors.
