Synthesis of Inconel Based Composites by Additive Manufacturing: A Mini-Review

Abstract

The study is a brief review of the synthesis of Inconel-based composites using additive manufacturing routes with the aim of identifying grey areas for further research. The study first examined the characteristics of Inconel alloy and its defects, thereby establishing the need for reinforcement by the addition of second-phase particles. Different reinforcement materials were discussed as well as different 3D manufacturing routes. The review also presented some results from scholarly works. The study showed that the process parameters and the route of fabrication are two determinants of the integrity of the synthesised composites. The study also emphasised the relevance of reinforcement to the improvement of the integrity of materials. The study recommends further research into the fabrication of Inconel/pure metal matrix composites to enhance the machinability of Inconel alloy and increase the fabrication of metal additive manufacturing machines to increase technology adoption, especially in third-world countries.
