Project A1 explores and explains the mechanical properties of single crystal Co- and Ni-base superalloys at elevated temperatures. In the third funding period, project A1 explores the relations between yield stress anomaly and γ/γ’-microstructure, the microstructural origin of creep transients after stress and temperature changes, the effect of deviations from crystallographic target directions on the macro (creep specimen) and micro scale (dendrite directions), the influence of the chemical compositions of phases on creep and the anisotropic damage evolution during multiaxial creep loading.
