Applications

Tantalum Aluminum Carbide (Ta4AlC3belongs to the family of Mn+1AXn (MAX) phases with more than 80 members. These are layered, machinable, nanolaminated ternary carbides, nitrides and borides, where M is an early transition metal, A is an A-group element, mainly from groups 13–16 and X is C or N or B. These compounds possess hexagonal crystal structure with space group P63/mmc (space group number: 194), where M atoms are in a near closed packed arrangement and are intercalated with A-group atomic layers, with the X-atoms residing in the octahedral sites between the M layers. These atomic arrangements give the MAX phases an effective laminated layered structure that leads to the naming of the MAX phase as nanolaminates. MAX phases possess a unique combination of properties, both metallic and ceramic in nature due to the layered structure. Metallic properties can include good thermal and electrical conductivities, good thermal shock resistance, excellent damage tolerance, and good machinability. Ceramic properties include low density, elastic rigidity, oxidation and creep resistance, and the ability to maintain the strength up to very high temperatures.

The bulk modulus of Ta4AlC3 was calculated to be 261 GPa and Ta4AlC3, so far, consists of the highest M for any single-phase and non-solid solution MAX. It was found that Ta4AlC3 exhibits a combination of improved mechanical properties, good damage tolerance and excellent thermal shock resistance, which makes it a promising structural material.
