Mechanical Properties of Spun Castings of Multicomponent Bronze Depending on the Casting Conditions

Abstract:

The paper is devoted to the study of the multicomponent lead-tin bronzes. The data on the influence of rotational velocity of a casting mould and the temperature of melt pouring on the structure and mechanical properties are presented in the article. The results of mechanical tests and studies of the microstructure allowed determining the optimal conditions of obtaining the castings with high strength characteristics. The conducted researches show that the maximum values of strength (σ_V=280–290 MPa) and impact strength (КС=2.7–3.2 KJ/cm²) are provided at the pouring temperature of 1150–1200 ̊С and rotational velocity of a casting mould equal to 1200 rpm.
