✦ Synopsis

Creep data, at 973 K and stresses between 355 and 512 MPa, in flat specimens of PE-IO nickel-base superalloy are reported. The data have been interpreted in terms of a constitutive equation based on a creep model involving dislocation climb and cross-slip over the strengthening phase. Strain-rate sensitivity and apparent activation energy have also been measured and analysed in the frame of the proposed model.

Tensile creep tests in the [011] direction have been performed on two specimens of SRR99 at 1173 K under a load of 300 MPa. The microstructure was analysed by transmission electron microscopy investigations after plastic strains of 0.1% and 0.29%. At both strains, the 7' phase is not sheared by disl

## Abstract Various heat treatments of the single‐crystal nickel‐base superalloy SRR99 have been carried out to produce a wide range of initial Ξ³β€² phase morphology. The cavitation damage has been studied after creep fracture at 850Β°C and stresses between 400MPa and 650 Mpa. The crep fracture surfac

## The resonance Raman profile for the Schiff-base complex N,N'-bis(salicylaldehyde)-odiaminobenzene nickel(H) has been measured at 290 and 10 K and the main peaks assigned. A broad fluorescence with a maximum at ca. 672 nm reduced the sensitivity of some measurements at room temperature but at 10
