· Ti3AlC

Ti3AlC is a ternary titanium aluminum carbide compound belonging to the MAX phase family—layered ceramics combining metallic and ceramic properties. This material exhibits unusual mechanical behavior: it remains damage-tolerant and machinable despite ceramic hardness, making it valuable where traditional ceramics are too brittle. Primary applications include high-temperature structural components, wear-resistant coatings, and thermal management systems in aerospace and power generation; researchers are also exploring its potential in composite reinforcement and electrical contact materials due to its thermal and electrical conductivity.
