Research Abstract

Domestic and international research collaboration has been made on TFGR (Toughened, Fine Grained, Recrystallized) tungsten-based materials in order to examine their applicability to divertor material. It is found that TFGR W-1.1%TiC and W-3.3%TaC exhibit more satisfactory performances from the viewpoints of various thermo-mechanical properties including the ductile-brittle transition temperature, response to thermal shock and thermal fatigue loading, and irradiation tolerance behavior against energetic particle irradiations and hydrogen isotope plasmaexposure. A more time saving and economical fabrication method has been established.
