Abstract
The contribution of intergranular γⲠprecipitates on the damage accumulation of the powder metallurgy superalloy N18 has been investigated. Electron microscopy investigations tend to link the deformation of primary precipitates to γ particles forming within primary γⲠprecipitates. Indeed, these fine ductile particles can act as dislocation sources. The plasticity of primary precipitates is, thus, assisted by the presence of γ particles and deformation incompatibilities are consequently increased at γ/γⲠinterfaces.
