The Relationship

To investigate the fatigue property of carbon structural steel in theory, the microstructure and properties of quenched martensite must be studied in detail. In this paper, the electronic structure and mechanical properties of carbon structural steel in quenched state were calculated by the empirical electron theory of solids and molecules (EET). The relationship between electronic structure parameters and mechanical properties of martensite was investigated. The mechanical properties of quenched carbon structural steel were calculated theoretically, and the result of theoretical calculation is consistent with the experiment result.

The Impact

Striking difference in density between the oxide and the steel results in difficulty in preparing oxide dispersion strengthened steel with large size parts or materials. In this research, Al2O3 and TiO2 particles were initially milled with the 20 steel, and then the mixture was heated to a molten state to form a master alloy, which was used as a raw material for further preparation of the object steel. It was found that homogeneous distribution of the oxide particles was obtained in the mass production of the steel. Moreover, the obtained 45 carbon structural steel presents fine microstructures, together with improved mechanical properties, especially the impact ductility. This should be attributable to the transformation from the introduced micro-size oxide particles to the nano ones, which act as heterogeneous nucleants that play an important role in grain refinement and dispersion strengthening for the steel, during the remelting of the master alloy.

Impact Viscosity

Physical and mechanical properties of the polymeric sand used as floor covering in cattle stalls were investigated. Samples of the polymeric sand were tested under static and dynamic stress, an impact test was done, mechanical characteristics were measured, and the material structural efficiency was evaluated. The polymeric sand tile appeared strong, reliable and durable material. The study material exhibited viscoelasticity. The polymeric sand samples demonstrated impact viscosity in the range 242,3– 548,3 kJ/m2 . The figure was 3,5–13,7 times higher than that of gray cast iron and was comparable with some classes of carbon structural steel. Mechanical properties of the polymeric sand were analysed. The characteristics revealed in the analysis can be used in dimensioning and designing products made from polymeric sand under various strength indices.
