钨是上级在物理和机械性能优于其他材料作为未来聚变反应堆的高热通量组件。改善其低温脆性、再结晶脆性和辐照脆性是该金属的关键问题。合金设计和显微组织控制，以实现同时和显着改善这些脆化的描述，并适用于钨和钼，具有非常相似的性能，钨。应用的结果是为每个脆化，相当成功。重点放在RIDU（辐射诱导延性化）的发生，因为RIDU有望提供解决严重的辐照脆化的方案，这是暴露在聚变环境中的结构材料的最关键的问题。
Tungsten is superior to other materials in physical and mechanical properties for use as high heat flux components in future fusion reactors. The key issue of the metal is to improve the low temperature embrittlement, the recrystallization embrittlement and the irradiation embrittlement. An alloy design and microstructure control for achieving simultaneous and significant improvements in those embrittlements are described and are applied to tungsten and molybdenum which has quite similar properties as tungsten. The result of the application is presented for each of the embrittlement, with considerable success. Emphasis is placed on the occurrence of RIDU (Radiation Induced Ductilization) because RIDU is expected to provide the scenario to overcome severe irradiation embrittlement that is the most crucial problem for structure materials exposed in fusion environment.
