Abstract

Results of metallographic studies of the microstructure of single crystals of alloy VZhM4-VI with residual content of lanthanum varied from 0.0002 to 0.026% after a complete heat treatment and after testing for long-term strength are presented. The mechanism of the action of lanthanum on the formation of nanostructure in single crystals of VZhM4-VI is studied. It is shown that creation of nanostructure in the alloy raises its high-temperature properties.
