Sažetak
The paper considers the effect of titanium carbide nanopowder (hereinafter referred to as the nanopowder material, NPM) on the structure and properties of medium-carbon heat-treatable steel containing vanadium, niobium, molybdenum and chromium. The titanium carbide nanopowder with dispersion of 80-90 nm in the amount of 0,08 % was introduced into steel before casting. After heat treatment, the prototypes were tested for hardness and wear resistance. The results show that in the experimental samples these properties are improved, which is associated with changes in the structure. The metallographic analysis of the structure (interstitial phases) was performed using ThixometPro software (Russia). In the analysis such parameters as the average size and the perimeter of interstitial phases, their shape and total relative occupied area were estimated. The results show that introducing the NPM leads to decreasing the size of interstitial phases and increasing the sphericity of the shape. Such structural changes increase hardness and wear resistance.
