Furthermore, an in-depth analysis was conducted on the microstructural evolution during the deformation process. The results show that the peak flow stress increased with decreasing deformation temperature and increasing strain rate. The strain-compensated Arrhenius constitutive equation was established based on the true stress-strain curve, demonstrating a correlation coefficient of 0.990 and an average absolute relative error of 3.842 %. Microstructural analysis demonstrated that the high-angle grain boundary (HAGBs) proportion was observed to first increase and then decrease with rising deformation temperature at a strain rate of 0.01 s<sup>−1</sup>. A maximum HAGBs fraction of 59.4 % was achieved at 400 °C. Some η-phase particles dissolve, some growth from 8 nm to 30 nm at 400 °C. When the temperature increased to 500 °C, η-phase re-precipitation was observed, characterized by an increase in particle number and a reduction in particle size to 3 nm. The pinning effect on dislocations and grain boundaries was significantly enhanced, resulting in a corresponding suppression of dynamic recrystallization. At 10 s<sup>−1</sup> and 450 °C, during the hot deformation, dislocations were aggregated to form a “stepped” structure, which could emit dislocations and further form dislocation networks.

The results indicate that CMAS preferentially corrodes the DySZ from their grain boundary. The inherent grain boundary segregation characteristics of solute Dy atoms provided a convenient channel for grain boundary corrosion. The thermochemical reaction between DySZ and CMAS leads to DySZ destabilization, which carried out through in-situ phase transformation and dissolution-recrystallization processes. It is proposed that improving DySZ corrosion resistance can be achieved by introducing pentavalent stabilizers to reduce Dy segregation or promoting the crystallization precipitation kinetics of CMAS.

Traditional microstructural preparation techniques, such as mechanical polishing, chemical etching, and ion beam milling, suffer from limitations including surface damage, complex procedures, and low efficiency. In contrast, glow discharge sputtering (GDS) operates in a high-pressure argon atmosphere (several millibars) and utilizes a wide-angle, low-energy argon ion beam to achieve uniform large-area sputtering with minimal material damage and high preparation efficiency. More importantly, the sputtering yield differences at grain/phase boundaries in GDS lead to selective sputtering behavior, which directly reveals the material's original microstructure, thereby eliminating the two essential steps of polishing and etching in traditional metallographic preparation. Commercial GDS instruments are exclusively designed for chemical composition analysis, lacking microstructural preparation capabilities. Furthermore, their restricted anode cylinder dimensions prevent them from meeting large-area preparation requirements. This study first employs numerical simulations to analyze glow discharge cathode sputtering behavior, confirming GDS's capability to preserve the material's original microstructural characteristics. Building upon this foundation, we designed and constructed a dedicated GDS apparatus for microstructural preparation, incorporating a successive approximation control algorithm to stabilize the glow discharge process. In practical applications, the integration of GDS with electron backscatter diffraction (EBSD) enabled three-dimensional reconstruction and visualization of GH4169 polycrystalline superalloy grains, revealing their three-dimensional morphology and spatial distribution. Additionally, GDS demonstrates versatility across various materials and characterization techniques. It significantly enhances microstructural image quality in EBSD, metallographic, and backscattered electron (BSE) imaging for materials including martensitic heat-resistant steel, T2 copper, and GH4096, effectively replacing polishing and etching in certain applications.
