科研项目
一、氢氦协同作用下过渡金属碳化物中缺陷形成及演化机理的模拟研究(国家自然科学青年基金青年科学基金,**)
项目概述:过渡金属碳化物(TMC)具有熔点高、热稳定性好、耐腐蚀、高热导率及低中子吸收截面等优良性能,是聚变堆重要的候选结构材料。然而在聚变反应环境中,大量H、He嬗变产物进入材料内与缺陷相互作用,聚集成泡,造成材料力学、热学性能下降,威胁核反应堆的安全稳态运行。本项目拟采用第一性原理计算方法对TMC从辐照初期本征缺陷产生,H、He与缺陷协同作用的动力学行为,到后期缺陷团簇处于热平衡态的整个过程进行系统的研究,细致深入地探索不同价态本征点缺陷对材料电子性质、结构稳定性的影响;H、He同性/异性聚核和解离机制及其协同扩散的微观物理机制,阐明H、He积累过程对弱化TM-C层间结合作用的规律,从静态和动态两方面揭示H、He协同作用对诱导材料内微裂纹形成及扩展的机理,总结H、He在TMC中扩散的一般规律,为设计和开发新型核结构材料提供有效的参考。
二、等离子体与典型壁材料相互作用的机理研究 (校博士基金,16zx7153)
研究适合国际热核试验堆要求的关键材料是目前聚变研究的热点、难点和前沿课题,而问题的解决取决于对等离子体与壁材料相互作用过程和机理的深入理解。在聚变反应过程中,面向等离子体材料(PFMs)将受到高热流等离子体的强烈辐照,同时也受到氢(He)、氦(He)粒子的轰击及其扩散、滞留和起泡的危害,因此有必要对H/He气泡在材料内的形成机制进行研究。目前PFMs的候选材料主要有钨、碳基材料(石墨、C/C复合材料),铍(Be)、钼、碳化硅(SiC)和碳化硼等。实验发现SiC、Be在遭受高通量H/He辐照后会在其表面产生气泡。这些气泡的产生和材料与杂质原子间的相互作用有关,特别是材料中的点缺陷,线缺陷和面缺陷等. 基于上述考虑,本项目研究了H/He原子与核材料SiC、Be间的相互作用以对材料结构性能的影响,利用第一性原理计算方法解释H/He与SiC、Be间的相互作用、杂质缺陷形成过程以及微观扩散行为,由于H、He外层电子结构的不同而在SiC材料中的稳定占据位、扩散方式不同;通过建立不同的物理扩散模型,研究了H、He在SiC中的扩散行为,给出了其扩散系数,结果与实验值吻合的很好,并解释了部分SiC辐照损伤的微观物理机制。
