Effect of δ-Ferrite on the Properties of Martensitic Steels

Effect of δ-Ferrite on the Properties of Martensitic Steels

The causes of formation of cracks in turbine vanes from high-chromium steels of martensitic class are studied. Spectrum, fractographic, and metallographic analyses of test pieces cut from turbine rotor blades in the state as delivered and after service are performed.
