Ti₃AlC₂/2024Al composites with a co-continuous structure were successfully fabricated from 2024Al powders and Ti₃AlC₂ porous preforms (with porosity of 48%, 41% and 35%, respectively) by pressureless infiltration at 930 °C. Long-rod like Al₃Ti was in situ formed due to reaction of Ti atoms de-intercalated from Ti₃AlC₂ and liquid 2024Al, which interpenetrated with Ti₃AlC₂ to form a new continuous framework. The mechanical properties in relationship with the initially different volume fractions of Ti₃AlC₂ and 2024Al at room temperature and high temperature were investigated. At room temperature, 59 vol%Ti₃AlC₂/2024Al has the best comprehensive mechanical properties, with the flexural strength of 510 MPa, compressive strength of 729 MPa, and compressive strain of 5.49%. Due to the co-continuous structure and the excellent high temperature of Al₃Ti, all samples exhibit well mechanical properties at 300 °C. Among them, 52 vol%Ti₃AlC₂/2024Al has the best performance with the ultimate compressive strength of 532 MPa, which is only 18.7% lower than room temperature. And even at 400 °C,it still has an objective compression strength of 394 MPa due to the highest content of Al₃Ti. In addition, after quenching from 400 °C to room temperature, the residual flexural strength of 52 vol%Ti₃AlC₂/2024Al can be reached to 450 MPa with the mere reduction rate of 7.4%. And no cracks are observed at the boundary of each phase, which means the good thermal shock resistance of the composites.

以 2024Al 粉末和 Ti ₃ AlC ₂多孔预制件（孔隙率分别为 48%、41% 和 35%）在 930 °C 下通过无压渗透成功制备了具有共连续结构的Ti ₃ AlC ₂ /2024Al 复合材料。由于从Ti ₃ AlC ₂脱嵌的Ti原子与液态2024Al反应，原位形成像Al ₃ Ti这样的长棒，与Ti ₃ AlC ₂相互渗透形成新的连续骨架。力学性能与初始不同体积分数 Ti ₃ AlC _{2 的关系}和 2024Al 在室温和高温下进行了研究。室温下，59 vol%Ti ₃ AlC ₂ /2024Al的综合力学性能最好，抗弯强度为510 MPa，抗压强度为729 MPa，压缩应变为5.49%。由于 Al ₃ Ti的共连续结构和优异的耐高温性，所有样品在 300 °C 下都表现出良好的机械性能。其中，52 vol%Ti ₃ AlC ₂ /2024Al性能最佳，极限抗压强度为532 MPa，仅比室温低18.7%。并且即使在 400 °C 下，由于 Al ₃含量最高，它仍具有 394 MPa 的客观抗压强度蒂。此外，从400℃淬火至室温后，52vol %Ti ₃ AlC ₂ /2024Al的残余抗弯强度可达到450 MPa，仅降低7.4%。且各相边界处均未观察到裂纹，表明复合材料具有良好的抗热震性。
