Abstract
With the rapid development of science and technology, the requirements for material performance in fields such as defense and military industry are getting higher and higher, and it is becoming more and more difficult to meet multiple performance requirements with a single material at the same time. Inspired by the special structure of shells, Metal-Intermetallic-Laminated composites (MIL) with composite, low-cost, and multifunctional properties have been prepared to combine the performance advantages of each component to achieve properties that cannot be achieved by a single material. In this paper, Fe/FeAl laminated composites were prepared by stacking pure Fe foil and pure Al foil alternately and using a vacuum hot-pressure sintering process to first consume all the Al layers by reacting at 655°C for a period of time, and then ramping up to 950°C for high-temperature annealing with different holding times. The microstructure and phase composition were analyzed by SEM and EDS, and the static and dynamic compressive strength and failure strain of the laminated material were measured by a universal testing machine and Hopkinson rod.
