Titanium Tungsten Composite Plasma Material
The ITER device is a superconducting tokamak can produce large-scale nuclear fusion reactions, aims to create a clean and sustainable energy future of mankind. ITER uses deuterium and tritium to produce nuclear fusion. Deuterium and tritium fusion in the circulation with millions, tens of millions of billions of temperature, the circulator must be strengthened by high temperature resistant metal, from the engineering point of view, material problems determine the success or failure of fusion energy development. In fusion materials, a very important type of material is plasma facing material (PFMs), and the general requirement for PFMs is: high temperature resistance, low sputtering, low hydrogen (tritium) retention and compatibility with structural materials. Tungsten is considered to be the most promising PFMs material, which can meet many requirements in this harsh environment. However, tungsten is facing severe brittleness because of its own structural characteristics. Therefor...
