Abstract
The possibility to use self-propagating high-temperature synthesis (SHS) for obtaining stable icosahedral quasi-crystals in the system 65 at. % Al + 20 at. % Cu + 15 at. % Fe was established as a result of X-ray and electron microscopy investigations, both for a mixture of the initial metal powder mixture and after their mechanical activation for a short time. Icosahedral quasi-crystals formed during SHS are shaped as pentagonal dodecahedrons 2
