Abstract

SEM images of the graphene nanofilm in the matrix of AlMgGr composite and after it dissolution in 20% HCl. Raman spectrums of the graphene nanofilms in AlMgGr composite and the graphene films obtained after dissolution of the composite in 20% HCl.Composites based on Al-Mg alloy, reinforced with graphene nanofilms, were obtained by in situ synthesis under a layer of salt melt. Using SEM and HRTEM, the morphological and dimensional characteristics of the structural components of composites with different contents of graphene were studied. An experiment on dynamic compression of composites by the Kolsky method was carried out, dynamic properties were measured, and the evolution of a cast structure during high-speed deformation was considered. For the first time, the dynamic properties of composites under loading by plane shock waves have been determined. The dynamic properties of aluminum matrix composites are compared depending on the properties of the non-reinforced alloy.
