COMPARATIVE FATIGUE TESTS OF PT-25-90 STEAM TURBINE BLADES

SRAVNITEL'NYE USTALOSTNYE ISPYTANIYA LOPATIK PAROVOI TURBINY PT-25-90

The method is described and results of comparative fatigue tests of steam turbine blades made of the 1Cr13 ball-bearing Steel are presented. The blades were manufactured using the method of manual grinding and polishing in accordance with a serial technology as well as using the method of cold rolling instead of grinding and polishing of the blade profile. Results of fatigue tests of blades after tempering in a vacuum at the temperatures of 700, 640, and 300 degree are presented.
