摘要

为了进一步提高Ti-Al3Ti层合复合材料的力学性能，采用吸热半固态反应法制备了Ti-Al3Ti- al层合复合材料，并对其进行了准静态压缩试验、动态压缩试验和弹道侵彻试验。结果表明:在660℃下制备的Ti-Al3Ti-Al层合复合材料的抗压强度和破坏应变分别为1432 MPa和35%;复合材料的动态响应具有明显的应变速率效应，裂纹扩展呈“z”形。Ti-Al3Ti-Al靶的V50为509 m s−1。综上所述，与Ti-Al3Ti复合材料相比，Ti-Al3Ti- al复合材料具有更好的力学性能和抗渗透性能。

Evaluation of the compressive and anti-penetration properties of Ti-Al3Ti-Al laminated composites

In order to further improve the mechanical properties of Ti-Al3Ti laminated composites, the endothermic semisolid reaction was used to fabricate Ti-Al3Ti-Al laminated composites, and the quasi-static compressive test, dynamic compressive test, and the ballistic penetration test were conducted on these composites. The results showed that the compressive strength and failure strain of Ti-Al3Ti-Al laminated composites prepared at 660°C are 1432 MPa and 35%, respectively. The dynamic response of these composites has obvious strain rate effect, and the crack grows in the shape of “Z.” The V50 of Ti-Al3Ti-Al targets is 509 m s−1. To sum up, Ti-Al3Ti-Al laminated composites have better mechanical properties and anti-penetration properties compared to Ti-Al3Ti laminated composites.
