Title: Accumulation of Corrosion-Fatigue Damage by Hydro Turbine Equipment Elements

Abstract

Questions are considered for evaluating material damage and substantiation of life on the basis of corrosion-fatigue crack development kinetics. Linear fracture mechanics are used for this approach suitable for large and small cracks, which makes it possible to include a nominal initial crack l0 among basic material properties. Calculated curves for fatigue in an aqueous medium based on 1010 cycles, and the curves for fatigue damage accumulation corresponding to 106 and 1010 cycles are provided for specimens with a cross section of 180X200 mm of steel 06Kh12N3D in rolled and cast conditions. Results are provided for evaluation of the life of during action of two-stage loading and repeated overloading.
