The object of research is
cast iron with lamellar graphite, modified with two types of modifiers – FeSi75 and FeSi40V7
The aim of research is to
determine the effect of vanadium on the mechanical properties of cast iron used for shaped castin
Paper title
Revealing the significance of the influence of vanadium on the mechanical properties of cast iron for castings for machine-building purpose
Keywords
cast iron for machine-building castings, modifier, alloying, vanadium, mechanical properties
Main scientific results imply the following
Use of vanadium in composition of FeSi40V7 within final content in cast iron at level of 0.04–0.078% can be expedient only if it is necessary to increase the hardness of cast iron due to the promotion of carbide formation during alloy crystallization
Scope of application
For further identification of mechanism for formation of properties and their control by purposefully regulating process of structure formation
Limitations for practical use
The results of the study are limited by the ranges of variation of the elements of the chemical composition when choosing the same modifiers
