Abstract
The paper presents the results of experimental study of vibration proof of gas turbine engine turbine blade roots made of ZhS30 monocrystal structure alloy under conditions of asymmetric vibration stress. The influence of different kinds of blade root surface hardening on the ultimate strength value was studied. Considerable reduction of ultimate stress after blade running has been found.
