The repairing parts were fabricated by PBF (powder bed fusion) using direct energy deposition (DED), interfacial cracks can occur at the interface between the substrate and the area to be repaired. Such interfacial defects are due to the thermal stress induced by the temperature gradient which results from repeated melting..... More
