报告题目：Internal stress analysis by synchrotron diffraction method
报告摘要：Dues to the materials fabrication and mechanical forming process, the internal stresses can be generated inevitably in mechanical components. The existence of those internal stress can affect largely the use properties of the materials and the mechanical components. So, it is necessary to dispose the technical solutions to identify and to quantify the internal stresses and to study their influences on materials behavior and on their durability. 3 orders of internal stresses can be defined and identified according to the observation scale in relationship with microstructure evolution and materials processing. Some analysis examples will be presented to show the relationship between the microstructure feature and the associated internal stress evolution of crystallin materials studied by synchrotron diffraction.

报告题目：Strategies for Improving the Lifetime of Air-plasma Sprayed Thermal Barrier Coatings
报告摘要：Air plasma sprayed (APS) thermal barrier coatings (TBCs) with typical lamellar structures are extensively employed in the hot sections of gas-turbine engines to elevate operational temperatures and improve engine efficiencies. However, these TBCs undergo degradation, leading to premature failure during service. Extending the lifespan of TBCs necessitates a comprehensive understanding of the degradation behavior and failure mechanisms involved. This study addresses the failure mechanisms associated with residual stress, growth of the thermally grown oxides, sintering, interfacial degradation, and calcium-magnesium-alumino-silicate (CMAS) attack. Moreover, recent advancements in strategies to mitigate the adverse effects of these life-limiting mechanisms will be reviewed, which include designing of interfacial and coating microstructure, and composition and processing modifications. Lastly, future directions and challenges for advancing APS TBCs will be presented.

报告题目：High-temperature CMAS corrosion in advanced aero engines: interaction behavior and protective strategies
报告摘要：Safe air travel activity requires clean flight corridors. But in Earth's atmosphere, particles (sand, dust and volcanic ash, referred to as CMAS) are often present. In excess cases, this contamination may endanger engine performance. and can even cause catastrophic failure. Consequently, it is essential to quantitatively delineate how CMAS undergoes melting and how it impinges upon and interacts with the hot-section components. This work aims to integrate a multi-disciplinary approach, drawing inspiration from biometrics (e.g., the lotus effect) and technologies used in coal combustion, thermal spraying, high-temperature interfacial science, and laser micro-machining to fully investigate the challenges imposed by CMAS corrosive interaction with jet engines.
