Chromium Titanium Aluminum Carbide MAX Phase Powder

Chromium Titanium Aluminum Carbide MAX Phase Powder

Chromium Titanium Aluminium Carbide MAX Phase Powder (Cr-Ti-Al-C) MAX phase powder is a sophisticated material belonging to the MAX phase family, known for combining metallic and ceramic properties. The general formula for MAX phases is Mn_nnAXn−1_{n-1}n−1, where M represents early transition metals (chromium and titanium in this case), A is an A-group element (aluminium), and X is carbon..

Properties and Characteristics

Thermal Stability: Cr-Ti-Al-C MAX phase powders are highly stable at elevated temperatures, maintaining their structural integrity under thermal stress.

Mechanical Strength: These materials exhibit a high degree of mechanical strength and hardness, characteristic of ceramics, while also offering some degree of plasticity and damage tolerance similar to metals.
