| Abstract Scope |
As metal additive manufacturing has been actively applied in many industries, much research has focused on the development of additive manufacturing for nuclear applications. However, the additive manufacturing of metal matrix composites for nuclear applications is still in the emerging stage because printable raw materials are not sufficient and the solidification of reinforcement-bearing metals during the additive manufacturing processes has not been fully established. In this study, the progress of additive manufacturing of various metal matrix composites by using a newly proposed surface modification and reinforcement transplantation technology is introduced. The manufactured metal matrix composites include Y2O3 dispersed alloys for radiation resistance, B4C dispersed Al composites for neutron shielding, and TiC dispersed Ni-base superalloy for high-temperature applications. Both the strengthening of the reinforcements and better solidification behavior improve the mechanical properties of the additive manufactured metal matrix composites, which is beneficial for structural and functional applications under extreme conditions. |
