Influence of cyclic thermal loading on brazed composites for fusion applications

摘要: Abstract Reactor grade graphite and molybdenum (TZM) were brazed with different high temperature brazes. The resulting tiles had a size of 50 × mm2 thickness 10 mm TZM 5 mm. composites have been tested in electron beam simulation for their thermal fatigue properties. parameters these tests chosen to match NET design specifications normal operation “slow” peak energy deposition. damage microstructural changes on the graphites brazes are discussed. Additional information is supplied X-ray diffraction data proving presence phases
