<p>To investigate damage evolution in Ti–Al metal-intermetallic laminated (Ti–Al MIL) composites after compression, Ti–Al MIL composites with different interfacial states and pore-distribution characteristics were fabricated by adjusting the hot-pressing temperature. The results indicated that the Ti–Al-620 composites consisted of TC4, Al, and an in-situ formed Al₃Ti phase. When the temperature was increased to 650&#xa0;°C, the consumption of the Al layers in Ti–Al-650 led to thickening of the brittle Al₃Ti layer and the formation of voids. Quasi-static compression tests showed that the thickened Al₃Ti layer increased the strength to some extent, but the unstable propagation of tunnel cracks markedly reduced the ductility. In addition, numerous voids in the Al₃Ti layer began to coalesce and collapse under compression, accelerating catastrophic failure. EBSD analyses revealed that tunnel cracks propagating along grain boundaries were initiated first in the Al₃Ti layer under relatively low compressive stress, and heterogeneous strain localization was observed in the crack-affected zone and near the interfaces. With increasing applied stress, cracks were formed at the Al₃Ti/Al boundary. In addition, the stress in the Al₃Ti layer decreased, and the load was progressively transferred to the TC4 and Al layers. This load redistribution enhanced ductility regulation, and delayed catastrophic failure.</p>
