Abstract

The superalloys on basis of Ni-Cr is meant for manufacturing rotor blades, disks and fastening details, which are used under 850 0С. These alloys additionally doped with Мо, Mo, W, Al and etc. for giving them a high-temperature properties. The main strengthening phase in these alloys is intermetallic phase, its nature, distribution pattern and dispersity [1].
