The theme of the final qualification work: "Identification of Â«structure-propertiesÂ» relationships in high-strength ductile iron grade EN-JS1050 with-out heat treatment."
This work is dedicated to the study of the structure of ductile iron speci-mens with spherical graphite, revealing of the relationship of structural param-eters with mechanical properties, and plotting of the dependencies of mechani-cal properties on the structure.
1. A literature review on the influence of high-strength cast iron struc-ture on its properties and methods for studying their relationships.
2. Examination of specimens, qualitative and quantitative assessment of the structure parameters, the plotting of one-parameter dependencies and models of mechanical properties.
The work was carried out on the basis of SPBSTU in the research and testing laboratory âMetallurgical Expertiseâ, where a metallographic analysis of research materials was carried out using optical microscopy. The structure parameters were evaluated using the Thixomet PRO image analyzer. As a re-sult, statistically significant âstructure-propertyâ relationships were revealed. They describe the values of tensile strength, yield strength and hardness in a ductile iron with a ferrite-pearlite matrix without heat treatment using micro-structural parameters.
