    摘要:

    輕核聚變反應產(chǎn)生的核能是解決能源問題的有效途徑。但核聚變堆中材料的工作環(huán)境苛刻，鎢憑借其優(yōu)異性能成為今后核聚變裝置中最有前途的備選材料，然而純鎢用于聚變堆時，存在韌脆轉(zhuǎn)變溫度較高、再結(jié)晶溫度低、輻照硬化和脆化以及難加工等問題。因此，引入鎢基材料以達到解決上述問題的目的。在此基礎上，介紹了鎢和鎢基材料在等離子體輻照、高熱負荷以及高能中子輻照作用下的損傷行為，討論了損傷機理，并指出了尚需研究的若干關(guān)鍵問題。

    Abstract:

    Producing fusion energy by light nuclear fusion reaction is an effective way to solve the energy problem. The materials in the reactor will face harsh working environment. Tungsten, with excellent properties, has become one of the most promising candidate materials in the future nuclear fusion device. But pure tungsten has some problems in the fusion, such as high ductile brittle transition temperature, low recrystallization temperature, irradiation hardening, embrittlement and difficult processing problem. Therefore, researching the tungsten-base material is used to solve the problems. On the basis of analysis of damage behavior of tungsten and tungsten-base materials under plasma irradiation, high heat load and high-energy neutron irradiation. Damage mechanism are discussed. Several key issues which need to be studied hereafter are put forward.
