Abstract
This article focuses on the study of phase stability and oxidation resistance of high-temperature alloys, aiming to gain a deeper understanding of the material behavior of high-temperature alloys in complex service environments and explore performance optimization strategies. The research background indicates that high-temperature alloys, as key materials in aerospace, energy, and chemical industries, have a direct impact on the reliability and lifespan of equipment due to their phase stability and oxidation resistance. The article first analyzes the current research status of high-temperature alloys and focuses on reviewing the progress made in the study of oxidation resistance in recent years. Subsequently, the influence mechanisms of alloy elements, heat treatment processes, and service environment on the phase stability of high-temperature alloys were discussed in detail, providing a theoretical basis for subsequent performance optimization. In terms of characterization and evaluation of antioxidant performance, this paper studied the oxidation kinetics behavior of high-temperature alloys, analyzed the formation mechanism of oxide films, and revealed the evolution law of the microstructure of the oxide layer, providing experimental basis for the improvement of antioxidant performance. Finally, this article focuses on the synergistic optimization strategy of phase stability and oxidation resistance in high-temperature alloys. By analyzing the mechanism of the influence of phase stability on antioxidant performance and the feedback effect of antioxidant performance on phase stability, a new approach for synergistic optimization of composition process structure was proposed. This strategy not only helps to improve the comprehensive performance of high-temperature alloys, but also provides useful references for material design and application in related fields. This study not only enriches the basic theory of high-temperature alloys, but also provides scientific basis and technical support for the performance optimization and practical application of high-temperature alloys.
