Sm3AlC
metal· JVASP-15757· Sm3AlC
Sm₃AlC is a ternary intermetallic compound belonging to the MAX phase family, which combines metallic and ceramic characteristics through a layered crystal structure of samarium, aluminum, and carbon. This material class is primarily investigated in research and advanced aerospace contexts for applications requiring simultaneous metallic conductivity and ceramic-level damage tolerance at elevated temperatures. Its notable distinction lies in the MAX phase architecture, which enables unusual properties such as machinability, thermal shock resistance, and damage recovery—making it a candidate for next-generation structural components where conventional ceramics or superalloys reach their performance limits.
