The anisotropic fatigue properties of three Ni-based SX superalloys (AM1, CMSX-4 and MC-NG) were investigated in the very high cycle regime at 20 kHz, R = ?1 750 °C. testing shows that [111] orientation has higher lives stresses lower low compared to standard [001] orientation. At stresses, resolved shear stress on octahedral slip systems explains anisotropy effect. pseudo-cube matrix becomes p...

The COnductor-like Screening MOdel of solvent-solute interactions of Klamt and Schüürmann, COSMO, at the semiempirical AM1 level of MO calculations, augmented by limited singles and doubles configuration interaction, proves useful for the study of solvent induced shifts of fluorescence spectra. Optimization of geometry of ground S0 and excited S1 states for each solvent separately provides esti...
