Process hybridization : DED with thin sheet metal / welding
➢ Maintenance and Repair of mechanical structures : New modes of repairs (alternative),
➢ 1st results without thermal treatment
▪ Young modulus = 107 MPa
▪ Elongation = 10%
▪ Yield strength = 880 MPa
▪ Ultimate strength = 1 GPa
➢ Results with thermal treatments
▪ Elongation (Tth, HIP) = 10% , 15%
▪ Yield strength (Tth, HIP) = 930 MPa , 830 MPa
▪ Ultimate strength (Tth, HIP) = 1 GPa, 920 MPa
