先进复合材料

       铝/镁基轻金属复合材料（MMCs）和陶瓷基复合材料（CMCs）由于质量轻、机械性能高，在航空航天、武器装备、核能和轨道交通等领域具有广阔的应用前景。然而，目前金属基复合材料的强韧化都是基于阻碍位错运动的机理，因此，陶瓷颗粒增强的铝/镁基轻金属复合材料有两大不可克服的缺点：（1）在提高强度的同时，牺牲了材料原有的延展性；（2）强度提高受到限制，无法满足很多应用需求。与以往的材料设计理念不同，近年来我们发展了非均匀结构、原位强化、混杂强化、层错/微孪晶强化的复合材料，并初步证明这类新材料具有更好的综合力学性能和全新的增韧/增强机理。

       颗粒增韧陶瓷基复合材料虽然具有工艺简单、成本低的优势，但是它们的力学性能还无法满足极端环境的应用需求。近年来我们围绕陶瓷基复合材料的仿生设计、晶界工程和缺陷工程等开展了相关研究，初步实现了陶瓷基复合材料的显微结构优化设计和力学性能提升。我们的研究将集中在：

o   从理论上研究先进复合材料的强韧化机理，建立微观力学模型；

o   建立微观机理与宏观性能之间的联系，为新型复合材料设计建立基础；

o   研发相应的材料制备和加工工艺，研究制备工艺对材料性能的影响，为材料的应用奠定基础；

o   设计/制备各类具有所需机械性能的先进复合材料，并开发其在各领域的应用。

场辅助材料制造技术

       先进陶瓷材料在很多领域具有广泛的应用前景，但制备高质量的陶瓷产品却不是一件容易的事情，其主要原因在于陶瓷材料的烧结和加工远比金属材料复杂和困难。 近年来，场（电场，磁场，力场等）辅助陶瓷烧结、合成、成型和连接技术在国际上受到广泛关注，并发现了诸多特殊的且非常有意思的现象。例如，在脉冲直流电场下，微米粉体原料可以制备出致密的纳米晶陶瓷；高压弱直流电场能够显著降低烧结温度，缩短致密化时间；循环应力可以得到力学性能大幅提高的陶瓷。然而，场辅助制造技术仍然处于摸索阶段，许多现象至今无法解释和应用。我们的研究将集中在：

o   从理论上理解各种场引起的快速传质机理；

o   在制造过程中通过多场耦合作用实现对材料的微观结构控制；

o   采用场辅助制造的方法制备高性能的氧化物、硼化物和碳化物基复合材料；

o   研发在航空、航天、核能，以及轨道交通等领域应用的高性能材料。
