Abstract Scope |
Additively manufactured Inconel 718 is an important superalloy, which is used in aviation and nuclear industries owing to its superior mechanical stability and corrosion resistance at elevated temperatures. However, the related industries are looking for new material groups including of Ni-based metal matrix composites (Ni-MMCs) with better thermomechanical properties than their conventional counterparts. It is challenging to produce Ni-MMCs by conventional casting since the fine ceramic reinforcing NPs could not be uniformly distributed in the microstructure, leading to poor mechanical properties.Therefore, there has been a growing interest in the development of Ni-MMCs via additive manufacturing.On the other hand, ZrB2 is a transition diboride such as a frequently used reinforcing particle TiB2 but with a 300 ◦C higher melting temperature (Tm: 3246 ◦C).Within this context, we produced ZrB2 particle reinforced Inconel 718 MMC’s via laser powder bed fusion (LPBF) and compared their microstructural and tensile properties with the unreinforced In718 ones. |
