Abstract 14Cr-4.5Al ODS steels were prepared by adding Y2Ti2O7 and Y2O3 nanoparticles respectively. Bilayer-structure corrosion scales were formed while the Y2Ti2O7-ODS steel showed a lower mass gain of 108.1 mg/dm2 in SCW for 1500 h. Compared with Y2O3, Y2Ti2O7 with finer size and higher number density exhibited more effective hindrance impacts on the diffusion of ions. Furthermore, adding Y2Ti2O7 in the ODS steel can provide more zero valent Al to form alumina film through inhibiting the forma...

Abstract Some mechanical property parameters of steel corrosion products require detailed examination in order to analyze cracking process of concrete with numerical models. Microstructural and micromechanical investigations on corrosion products were performed by combined analysis by scanning electron microscopy, Raman spectroscopy and nano-indentation techniques. The corrosion products were identified to be goethite, lepidocrocite, akaganeite, maghemite and magnetite. The local Young’s modulus...

Abstract In this study, large α-Al2O3 particles were prepared by a novel surface pre-agglomeration (SPA) treatment on the surface of MCrAlY bond coats. These large α-Al2O3 particles eventually improved the oxidation resistance of the LPPS and APS MCrAlY bond coats by a factor of three and eight times, respectively. Results confirm that these large α-Al2O3 particles resulted from the agglomeration of the as-deposited alumina film during the SPA treatment. Based on the characteristics of alumina f...

Abstract The onset of sub-critical crack growth during slow strain rate tensile testing (SSRT) is assessed through a combined experimental and modeling approach. A systematic comparison of the extent of intergranular fracture and expected hydrogen ingress suggests that hydrogen diffusion alone is insufficient to explain the intergranular fracture depths observed after SSRT experiments in a Ni–Cu superalloy. Simulations of these experiments using a new phase field formulation indicate that crack ...

Abstract C/C-ZrC-SiC composites were fabricated by carbothermal reaction of hydrothermal co-deposited oxides and resulted in homogeneous microstructure. The fracture behavior passed from pseudo-plastic to brittle fracture with the increase in ZrC/SiC molar ratios. The composites with a molar ratio of ZrC/SiC≈2:1 presented outstanding ablation resistance with a mass ablation rate of 0.06 mg cm−2 s−1 and a linear ablation rate of 0.13 μm s−1. The optimal ZrC/SiC molar ratio provided a suitable bal...

Abstract The anti-corrosion behaviors of SLM-processed 316L stainless steel (SLMed-SS) with amorphous alloy additive (SLMed-composite) have been investigated, where the pitting of SLMed-composite is easy to be suppressed compared to that of SLMed-SS particularly once the pitting occurred. In addition, the pitting incubation time of SLMed-composite is confirmed to be longer than that of SLMed-SS by potentiostatic polarization under the same potential. More importantly, we confirm that the improve...

Abstract Accelerated corrosion of boiler equipment remains a challenge for efficiently utilising biomass- and waste for power production. To overcome this challenge a better understanding of the influence of corrosive species present is required. This study focuses on the influence of KCl(s) on corrosion of Fe-2.25Cr-1Mo at 400 °C. This is done by well-controlled laboratory exposures and detailed microstructural investigation with ion and electron microscopy (TEM, FIB, SEM, EDX, XRD, TKD). The s...

Abstract The CO2 corrosion behavior of sensitized and non-sensitized 304 and 316 stainless steels in the absence and presence of H2S was investigated using cyclic polarization and electrochemical impedance spectroscopy techniques. The sensitization resulted in significant negative shift on pitting potential for both alloys. The general CO2 corrosion rate of sensitized and non-sensitized samples was not significant. However, increasing H2S concentration up to 200 ppm resulted in severe increase i...

Abstract The influence of chloride on the corrosion behavior of Al-Zn-Mg alloy was explored, and the results are explained using the Point Defect Model (PDM). Cyclic potentiodynamic polarization was utilized to study the breakdown behavior, and the corrosion morphologies for different chloride concentrations were observed using scanning electron microscopy, and the depth of the corrosion pit was measured using laser confocal microscopy. Furthermore, SPM and XPS were used to further analyze the b...

Abstract The influence of 9Cr-1Mo sample thickness on oxidation and carburization kinetics was investigated. State of the art characterization and modeling techniques were employed to investigate the oxidation and carburization behavior. Within the tested exposure times, the sample thickness did not affect oxidation kinetics, products, or the carburized microstructure. The carburization profile measured by various techniques were in good agreement. From these measurements, a quantitative carburi...
