Summary: The corrosion behavior of TiAl-Nb alloy in liquid zinc was investigated and found to exhibit excellent corrosion resistance, with a corrosion life of 130 days, nearly six times longer than that of WC-Co coating. The corrosion process was divided into an incubation period and a rapid corrosion period, with the corrosion life primarily depending on the incubation period. The concept of incubation-style corrosion was proposed for the first time. Surprisingly, samples cut by wire electrical discharge machining showed much higher corrosion resistance compared to polished samples, attributed to the surface effect.

Summary: This study investigates the metastable transformation behavior in a cast Ti-48Al-3Nb1.5Ta alloy during continuous cooling. The results show that a small amount of Ta promotes metastable transformations and reduces the cooling rates required. Crystallographic and kinetics studies reveal the nucleation mechanism of the Widmanstatten transformation. Thermodynamic analyses suggest that Ta may reduce the energy of the gamma phase boundaries to promote the nucleation of metastable structures.

Summary: This study investigates the high-temperature deformation and decomposition mechanisms of the alpha(2) phase in a beta-solidified TiAl alloy. The results show that beta(o) and omega(o) phases precipitate within the equiaxed alpha(2) phase at 800 degrees C, indicating the alpha(2) -> beta(o) -> omega(o) transformation. Additionally, gamma phase precipitates form within the beta(o) matrix, and the alpha(2) lamellae decompose into ultrafine (alpha(2) + gamma) lamellae and coarsened gamma lamellae through alpha(2) -> alpha(2) + gamma and alpha(2) -> gamma transformations, respectively. Furthermore, the omega(o) phase nucleates within the ultrafine lamellae via alpha(2) -> omega(o) transformation. However, at 1000 degrees C, the nucleation of beta(o) particles is sluggish due to the efficient release of internal stress via dynamic recrystallization (DRX). These findings suggest that the decomposition of the alpha(2) phase can introduce complex phase transformations in TiAl alloys with a high amount of beta-stabilizing elements.

Summary: This study investigates the microstructural evolution and dynamic recrystallization mechanism of a nickel-based superalloy PM EP962NP during isothermal compression at 1150 degrees C under different strain rates and strains. The results show that continuous dynamic recrystallization occurs when the strain exceeds 0.36. A processing window with high microstructure stability, including the evolution of DRX, y grains, and y' precipitates, is determined to be hot compression at 1150 degrees C with a strain rate of 0.001 s-1 and strains ranging from 0.69 to 1.20. In addition, the y' precipitates exhibit inhomogeneous sizes due to the interaction between dissolution and precipitation, with micron-scale blocky primary y' and nano-scale spherical secondary y'. Moreover, the abundant microstructural information related to the strain rates and strains can provide a reference for obtaining gradient microstructures through thermo-mechanical processes.

Summary: In this paper, the inhibiting effect of Mn and Cr elements on the precipitation of omega o phase in beta-solidified gamma-TiAl alloys is investigated. The results show that both Mn and Cr have an inhibiting effect on the omega o phase precipitation, with a more obvious effect in the alloy with Mn addition. The addition of alloying elements lowers the phase transformation temperature of omega o phase, making it difficult to precipitate at intermediate temperatures.

Summary: The gamma' phase plays a significant role in the deformation mechanism of nickel-based superalloys strengthened by solid solution. The microfracture behavior of the alloy depends on the stress and strain distribution between the gamma and gamma' phases under load. In this study, the in situ synchrotron radiation high-energy X-ray diffraction technique was used to observe the deformation process of the FGH96 nickel-based superalloy with a gamma' volume fraction of about 40% at 650 °C and 750 °C. The results reveal that the (111) reflection exhibits the highest stiffness and initiates plastic deformation first, while the (200) reflection carries a larger load. The gamma phase undergoes plastic deformation initially, followed by the transfer of load to the gamma' phase. At 650 °C, the plastic deformation of the gamma' phase is relatively higher, whereas at 750 °C, the gamma' particles mainly undergo elastic deformation with a small amount of plastic deformation.

Summary: High porosity Co-Al-Fe intermetallics with 3D-microstructures were successfully synthesized in one step via a thermal explosion reaction. The link between pore structure and permeability was investigated using 3D-XRM technology. The corrosion resistance of the samples with different Fe contents was studied at 900 degrees C under an oxygen/sulphur atmosphere for up to 120 h. The results showed that the samples maintained stable pore structure and intact internal matrices, attributed to the formation of a thin protective layer on the surface. In addition, inward diffusion of S resulted in the formation of FeS nodules.

Summary: In this study, an environmentally friendly volatile corrosion inhibitor, lysine salts (LA), was prepared between graphene oxide (GO) layers using an in situ intercalation technique. The corrosion inhibition effect of LA was evaluated, and it was found that LA-GO2 achieved a 99.3% corrosion inhibition efficiency after composition optimization. The inhibition of the electrochemical anodic process on the surface of mild steel was the main reason for the high corrosion inhibition efficiency of LA-GO2. The properties of the surface film on the corroded steel were also characterized in detail to understand the corrosion inhibition mechanism of LA-GO2.
