dc.description.abstractEN: Abstract. The results of studies aimed at improving the mechanical and operational properties of the Fe–Cu–Ni–Sn and Fe–Cu–Ni–Sn–VN composite materials obtained by powder metallurgy methods are presented. A comparative analysis of mechanical and tribological characteristics, including the determination of nanohardness, elastic modulus, friction force, friction coefficient, and volume of wear groove was performed. It was shown that the use of 3 wt% nano-dispersed VN powder in the 51Fe–32Cu–9Ni–8Sn charge, in which the grain size was ~2000–5000 nm, makes it possible to increase the nanohardness from 2.68 to 5.37 GPa and reduce the elastic modulus from 199 to 125 GPa. As a result, the parameters H/E and H3/E2, which describe the resistance of the material to the elastic deformation of failure and the resistance of the material to plastic deformation, increase by 3.3 and 20 times, respectively, and the friction force and the volume of the wear groove decrease by 1.8 and 16 times, respectively. The reasons for the change in the mechanical characteristics of sintered composites during nanoindentation and the different nature of their wear are discussed. The interrelation of the microstructure with mechanical and tribological properties is established. It is shown that the parameters H/E and H3/E2 can be used to predict the wear resistance of the composites under study.en
