Structuring the Ni Matrix with Ti–C Nanostructures Using Surface Chemical Reactions to Create a Composite with Improved Mechanical Properties

Modern technologies for the creation of metal matrix composites (MMCs) are based on the directional nanostructuring (reinforcement) of a metal matrix with ceramic nanostructures leading to reinforced materials with improved mechanical characteristics. MMCs’ development firstly requires to establish chemical and physical parameters that control the properties of solids of varying degrees of complexity and materials based on them. Experimental and theoretical studies of nanostructuring processes help to synthesize nanomaterials with controlled mechanical properties. In this work, composites where titanium carbide (TiC) nanostructures with a size of 1–2 nm are evenly distributed in the bulk Ni matrix were obtained using surface chemical reactions (SCRs). Surface reactions provide the absence of interphase boundaries.
