Research methods are mathematical modeling, physical experiment, methods of optical and electron microscopy, X-ray structural and elementary X-ray spectral microanalysis, identification methods, etc. Technological principles of spark-plasma sintering (SPS) of powder charge obtained using high-voltage electric-discharge powder preparation technology are developed. SPS temperature-time modes are determined for obtaining nanolaminates - Ti - Al - C system components with carbides, intermetallic phases and MAX phases (Ti2AlC - 35.33% wt; Ti3AlC2 - 64.67% wt.), having density close to theoretical, hardness of 4.5 GPa, elasticity modulus of 7.4 GPa and dynamic strength of 280 MPa. It is established that SPS associated heating rate affects the kinetics of densification, structurization and physicomechanical properties of disperse-strengthened metal-matrix composites of Fe-Ti-C (B) and Ti-Al-C systems should be not more than 10оS/s, at a current rise rate of ~ 25 A/s Product Description popup.authors Зайченко А.Д.
