Considerable steps to assess the structural capability of laser directed energy deposition (DED) aim to determine the viability of repair processes for integrally bladed rotors (IBRs). Two laser DED processes are under investigation in this study: wi

A major disadvantage regarding integrally bladed rotors (IBRs: also referred to as blisks) is the ability to repair damage. Since it is a single part, anything beyond a minor dent requires full removal and either an expensive replacement or a complic
