The first wall of 90WMoNiFe alloy facing the plasma is a key component in the controllable nuclear fusion device. It is directly exposed to the high-temperature and high-density plasma environment. The main function of the first wall is to withstand the thermal load from the plasma, particle flow impact and potential radiation damage, while ensuring the stable progress of the fusion reaction. 90WMoNiFe alloy was chosen as the material for the first wall because it has a series of excellent physical and chemical properties.
First, the alloy has excellent high-temperature resistance and is able to maintain structural stability and integrity at extremely high temperatures, thereby effectively withstanding the thermal load from the plasma. Secondly, 90WMoNiFe alloy also has good anti-corrosion and anti-radiation properties, and can resist damage to materials caused by high-energy particles and radiation in the plasma, extending the service life of the first wall.
In addition, the mechanical properties of 90WMoNiFe alloy are also very good, with high strength and good toughness, and can withstand various forces and stresses generated during the fusion reaction. These properties make 90WMoNiFe alloy an ideal material for making the first wall facing the plasma.
In a controllable nuclear fusion device, the design and manufacturing of the first wall are crucial to ensuring the smooth progress of the fusion reaction. The application of 90WMoNiFe alloy not only improves the performance and reliability of the first wall, but also provides strong support for the development of fusion technology. With the deepening of fusion research and technological advancement, the performance of 90WMoNiFe alloy facing the first wall of plasma will be further optimized and improved, laying a solid foundation for future fusion energy applications.
