为了预测长期锂化壁处理工艺对第一壁材料——钨的影响,本工作采用第一性原理计算,探讨锂、氦杂质原子在金属钨中的行为及其对钨金属材料力学和热力学性质的影响。计算结果表明,单一锂原子在钨晶体中倾向于占据替代位置,该替代锂原子和位于间隙位置的氦或其他锂原子之间皆存在较强的正结合能,而且当多个间隙氦或锂原子聚集在替代锂原子周围时,体系仍然具有正结合能。对钨晶体含有锂或氦多原子聚集体力学性能(体弹模量、剪切模量、杨氏模量、泊松比、柯西压力)的计算结果表明,锂或氦多原子聚集体的出现将导致钨材料的力学强度降低,韧(展)性提高。采用准简谐Debye模型对含有锂或氦多原子聚集体的钨材料的吉布斯自由能、等容热容、熵等热力学性质的计算结果表明,锂或氦多原子聚集体的出现也将导致钨金属体系的热力学性质发生变化,这将对钨金属材料的温度分布、杂质浓度等产生一定的影响。

托卡马克装置是实现可控热核聚变的主要装置之一,而第一壁材料在确保托卡马克装置稳定运行的过程中起着至关重要的作用.钨金属已被广泛使用作为第一壁材料,但是聚变反应产生的氦原子在进入钨晶体后易形成“氦气泡”和点缺陷,严重影响托卡马克装置第一壁材料的稳定性.首次设计将钨/石墨烷/钨体系作为第一壁材料.第一性原理计算结果表明,钨/石墨烷/钨第一壁材料中的界面可以捕获氦原子和空位,且能促进自填隙钨原子与空位复合,从而降低钨体相中的缺陷密度;弹性常数计算结果表明,石墨烷层的存在可以提高钨金属的柯西压力值(C')和各向异性因子(A),使第一壁材料的延展性得以提高,且不易出现裂纹,但是在相同温度下钨/石墨烷/钨第一壁材料的力学模量有所下降;利用准简谐德拜模型计算吉布斯自由能G^(*)、定容热容C_(V)、熵(S)等热力学函数结果表明,钨/石墨烷/钨第一壁材料的热力学稳定性与纯钨金属相比有所下降.
