Complex metallic alloys

Complex metallic alloys (CMAs) of complex intermetallics (CIMs) are intermetallic compounds characterized by the following structural features:

Most physical properties of CMAs show distinct differences with respect to the behaviour of normal metallic alloys and therefore these materials possess a high potential for technological application.

The European Commission funded the Network of Excellence CMA [1] from 2005 to 2010, uniting 19 core groups in 12 countries. From this emerged the European Integrated Center for the Development of New Metallic Alloys and Compounds C-MAC [2], which connects researchers at 21 universities.

Example phases are:
