Abstract Scope |
In this work, artificially damaged 1100 aluminum samples were repaired with wire-fed laser additive manufacturing technology and the mechanical properties were investigated. Various types of damage sites on the order of several cubic millimeters were systematically created to investigate the relationship between the damage size/shape and the repair performance. The damage sites were repaired with pulsed laser deposition additive manufacturing, and the repaired samples were tested at high strain rates using a light-gas gun. Post-mortem metallography was used to study the links between repair processing methodology, microstructure, and mechanical performance. Results show that optimal process parameters are critical for realizing effective repairs due to the dependence of damage morphology on the resulting microstructure. |
