Abstract
The peculiarities of short-term resistance to tension/compression, creep, long-term strength and thermal fatigue of single-crystal superalloys for different crystallographic orientations and temperatures are considered. The failure criteria are proposed using a unified measures equivalent stress (strain) for the cubic system, allowing to compute adequate strength and durability of single crystal materials under complex multi-axial inhomogeneous stress state, which is characteristic for gas turbine engine blades during the operation.
