    Dual-phase reinforcing approach provides a novel and efficient strategy for the fabrication of advanced aluminum matrix composites (AMCs). The devisable and desirable performance could be achieved by tuning dual-phase reinforcing system. However, it is still challenging to design a dual-phase reinforcing system with synergistic strengthening effect, especially for the laser powder bed fusion (LPBF) characterized by nonequilibrium metallurgical process.

    双相增强方法为制备高性能铝基复合材料(AMCs)提供了一种新颖且有效的策略。通过调整双相增强体系,可以获得可设计和期望的性能。然而,在非平衡冶金过程特征明显的激光粉末床熔合(LPBF)工艺中,设计具有协同强化效应的双相增强系统仍然具有挑战性。在这项工作中,我们设计并使用LPBF技术制备了含有20wt.%双相(TiN+AlN)颗粒增强纯铝的复合材料。TiN和AlN可以形成整个组成范围内的亚稳态三元Ti1-xAlxN固溶体,这是一种有前景的AMCs强化相。在双相(TiN+AlN)陶瓷粒子和激光熔化工艺的作用下,在激光制备的复合材料中观察到了新颖的微观结构。TiN颗粒表面形成了一个梯度层。这种界面结构可以作为陶瓷颗粒在铝基体中的锚点,有利于实现强界面结合和良好的载荷传递。除了这个梯度层外,还观察到均匀分散的Ti1-xAlxN纳米粒子析出,这可以有效阻碍位错运动并细化晶粒。此外,为了比较双相(TiN+AlN)强化的影响,并揭示其贡献,我们制备了纯铝和TiN/Al、AlN/Al复合材料进行对比研究。(TiN+AlN)/Al复合材料的抗拉强度达到约254 MPa,分别比TiN/Al和AlN/Al复合材料提高了约75%和81%。这种新颖的微观结构,包括梯度层和析出的纳米粒子,有助于(TiN+AlN)/Al复合材料实现高效的强化效果。
