用于核聚变装置的W/Cu穿管部件的制备与辐照性能研究
The manufacture of W/Cu mono-block PFCs for fusion device and its irradiation behavior
【摘要】 采用了两步热等静压法制备W/Cu穿管部件,即先用热等静压(930℃,100MPa,2h)在钨块的孔内壁上覆一层无氧铜作为中间层,然后再用热等静压工艺(600℃,100MPa,2h)把W/Cu复合块与Cu Cr Zr管串接起来。经过高热负荷辐照测试,部件经受住了1000次10MW·m-2高热负荷的辐照,满足使用要求。
【Abstract】 The W/Cu mono-block PFCs were manufactured by two-steps of hot isostatic pressing(HIP). The W mono-blocks were joined with a layer of OFHC and then joined to a Cu Cr Zr tube by means of HIP technology. The thermal fatigue testing of W/Cu mono-block PFCs were performed and the PFCs withstood 1000 cycles of heat loads up to 10MWm-2 with the cooling water of 4m·s-1, 20℃.
