Abstract: | Some results obtained in the course of structural investigations with the use of the methods of scanning electron microscopy
and X-ray structure analysis of operating temperature influence upon dynamics of the hardened state relaxation in the turbine
blade roots are discribed. Also considered are the data on determining the residual surface stresses by Davidenkov’s method
and that of the X-ray diffractometry. |
