Abstract Scope |
Laser powder bed fusion (L-PBF) has emerged as an emerging technology for fabricating graphene-reinforced metal matrix composites. The strength of the composites depends largely on the uniform dispersion of graphene in the metal matrix. Graphene, as a reinforcement, enhances the mechanical properties of the 316L stainless steel (SS316L) matrix. In this work, a comprehensive microstructural analysis is presented to describe the influence of graphene on the SS316L matrix. Additionally, it will address the contribution of graphene, in-situ segregations, and precipitations on the matrix. Transmission electron microscopy (TEM) is extensively used to understand the underlying phenomena. The interaction of dislocations with graphene and in-situ precipitates is also discussed in detail. Furthermore, several strengthening models are proposed to elucidate the contribution of graphene in strengthening the composites. Addressing these critical aspects contributes to a deeper understanding of the strengthening mechanisms in graphene-reinforced SS316L composites. |
