Abstract

The present study aims at enhancing the understanding of damage evolution mechanism in precipitation-strengthened Fe-Ni-Cr based steel (SUH660). Tensile deformation at room temperature, subsequent damage quantification and microstructural characterization was performed. The primary damage initiation sites were observed at inclusions and spots where dislocation slip impinges grain boundary. Early damage initiation was also observed.
