Experimental and simulation studies on damage mechanisms of tungsten and molybdenum under compressed plasma flow irradiation

Abstract: The failure mechanism of plasma-facing components (PFCs) under extreme plasma conditions relevant for fusion reactor were investigated. Here, edge-localized mode (ELM)-like transient thermal shock irradiation experiments were performed on tungsten and molybdenum using compressed plasma flow, and combined with thermal-mechanical analysis by means of finite element simulations to discuss the grain structure evolution, cracking behavior and variations of hardness. When ELM-like thermal shock irradiation was suffi… Show more
