本文以Al箔和TiBw/Ti复合箔为原料，通过堆叠和反应退火，设计并制备了由TiBw/Ti和Ti(Al)交替层组成的TiBw[Ti-Ti(Al)层状复合材料。层状复合材料的设计策略有助于实现低密度（4.33 g/cm(3)）、高屈服强度（722 MPa）和极限强度（783 MPa）以及室温（RT）断裂伸长率（8.22%）的良好结合。对层状复合材料强化机制的研究表明，约55.7%的强化源于固溶效应，而层状结构强化占22.0%，其余为TiBw增强材料。 (C) 2015 Elsevier Ltd. 保留所有权利。
In this paper, we designed and prepared TiBw[Ti-Ti(Al) laminated composites consisting of alternating layers of TiBw/Ti and Ti(Al), which were realized by using Al foils and TiBw/Ti composite foils as raw materials, stacking, and reaction annealing. The design strategy of laminated composites contributes to a good combination of low density (4.33 g/cm(3)), high yield strength (722 MPa) and ultimate strength (783 MPa), and elongation to fracture (8.22%) at room temperature (RT). Investigations on strengthening mechanisms of laminated composites show that about 55.7% of strengthening originates from solid solution effect, while laminated structure strengthening occupies 22.0%, and the rest is covered by TiBw reinforcements.
