Abstract

In this work the possibility of creating a new high-temperature heat-resistant matrix based on intermetallic compounds NiAl and Ni3Al. It is found that the alloys based on the new matrix have good heat resistance and low density. Under the conditions of high-gradient directional crystallization in the samples it was possible to form a directed dendritic structure, oriented along the axis of the samples, consisting of intermetallic NiAl and Ni3Al. In assessing the strength of them managed to get a fairly high strength and ductility.
