Investigating relationships between laser metal deposition deployment conditions and material microstructural evolution

Additive Manufacturing can be utilised for the repair and remanufacture of metallic components with reduced replacement costs and with the potential for better mechanical and wear resistance properties ensuring remanufactured components are better than or equal to originals. This paper presents the current data concerning Laser Metal Deposition deployment conditions and their relationship to material microstructure evolution and mechanical properties. The study highlights the need for experiments involving scan path geometry and topology and details the experiments currently in preparation
