According to the news from the Institute of Metal Research of the Chinese Academy of Sciences, aluminum-based composite materials have become the core structural materials in the aerospace field due to their high specific strength and specific modulus. However, constrained by issues such as high-temperature interface degradation and matrix softening, their service temperature has been limited to below 300℃ for a long time, severely restricting their application in high-temperature scenarios. To enhance their high-temperature service capabilities, in-situ aluminum-based composite materials with excellent metallurgical bonding interfaces have become the research focus. Recently, the research team of the Aluminum-Magnesium Materials Research Department of the Shenyang Materials Science National Research Center of the Institute of Metal Research of the Chinese Academy of Sciences proposed the defect-promoted "internal decomposition" mechanism of Ti2AlC (MAX phase). This strategy can break through the reaction kinetics bottleneck dominated by surface diffusion and solve the core contradiction of the difficulty in coordinating the size and volume fraction of the strengthening phase, successfully developing multi-level structure Al3Ti/Al composite materials with excellent high-temperature strength and modulus.
