Abstract
With the rapid development of industrial technology, the application performance of welding materials under extreme conditions has become a critical research area, especially in complex working environments such as high temperature, high pressure, and corrosive media, where traditional welding materials are increasingly unable to meet practical requirements. This study aims to evaluate the comprehensive performance of a novel welding material under extreme conditions and explore its potential application value. Through laboratory simulation of extreme environments, multi-dimensional methods including mechanical property testing, microstructural analysis, and corrosion resistance evaluation were employed to systematically investigate the behavior characteristics of this material under various temperature, pressure, and chemical medium conditions. The results indicate that this new welding material exhibits superior high-temperature strength, thermal shock resistance, and corrosion resistance, with significantly enhanced performance compared to existing similar materials. Particularly in high-temperature oxidation environments, the material demonstrates stable microstructure and a low oxidation rate, primarily attributed to its unique alloy composition design and grain refinement mechanism. Additionally, the study reveals that the material maintains good toughness under dynamic loading conditions, effectively resisting crack propagation. A key innovation of this research lies in the first introduction of nano-enhanced phases into the welding material system, which markedly improves its adaptability to extreme environments, providing theoretical support and technical references for engineering applications in related fields. Overall, this research not only broadens the design思路of welding materials but also lays an important foundation for the future development of high-performance welding materials.
