金属间化合物叠层复合材料（简称MIL）是模拟贝壳结构，将高硬度的金属间化合物与韧性良好的金属交替叠加获得的新型层状复合材料。成本较低且兼具多层化合物结构的不锈钢基MIL材料是极具潜力的叠层复合材料之一，其有望在武器装备防护领域获得应用。然而低温共晶反应获得的不锈钢基MIL材料中化合物层由Fe4Al13、Fe2Al5等富铝脆性化合物构成，使得MIL材料表现出脆性材料的特性，引起金属/金属间化合物界面应力集中。.本研究通过材料设计，以韧性FeAl相作为金属间化合物层与不锈钢交替叠加，利用共晶反应结合高温扩散退火的方式制备韧性不锈钢/FeAl基MIL材料。从初始箔材叠层结构设计、高温扩散退火界面反应机理以及韧性铁基MIL材料动态力学性能表现等方面开展研究。研究涉及扩散反应热力学、动力学以及层状结构动态力学行为等，将为层状复合材料制备及性能表征提供理论指导。

Metal-Intermetallic-Laminate (MIL) is designed to mimic the shells structure, which optimizes the unique properties of the constituent components by incorporating the high stiffness of the intermetallic phase with the high toughness of the residual metal. The lower cost with multi-layer structure of the Stainless Steel (SS)-based MIL composites makes them an attractive material for military protection structural applications. However, brittle Al-rich intermetallic phases such as Fe4Al13 or Fe2Al5 formed in the SS-based MIL by low temperature eutectic reaction, which leads to its brittle properties and stress concentration at metal/intermetallic interface...This study develop a ductile MIL composites: SS/FeAl-based MIL composites which will be fabricated by eutectic reaction together with high temperature annealing process. The study includes: design the stack structure of initial foils, interface reaction mechanism of high temperature annealing in Fe-Al system, dynamic properties of ductile SS/FeAl-based MIL. The research involved thermodynamic and kinetic of reactive diffusion, dynamic behavior of multilayered structure, which will provide theory guidance for preparing and properties characterization of MIL composites.
