Effects Of Production Conditions On Micro And Macro Structural Properties Of Compacted Graphite Cast Iron
Journal Title: Gazi Üniversitesi Fen Bilimleri Dergisi Part C: Tasarım ve Teknoloji - Year 2018, Vol 6, Issue 4
Abstract
This paper is prepared to show the effects of production conditions on the manufacturability and structural properties of Compacted Graphite Cast Iron (CGI) material. Since this material is intended for high speed brake disc production, 45-50% vermiculization is regarded as sufficient for suitability for the usage conditions. Because they require relatively good mechanical properties such as higher strength than these materials. For use in this work, we have developed a vermicularising material called Ver-Mat and added CGI specimens in the casting cruciple. For these purposes, the desired materials were produced by adding vermiculariser at different ratios. Subsequently, micro- and macro-structural changes were investigated by applying FeSi inoculants (0.3%, 0.5% and 0.8%) and 0.5 % Cu addition to the appropriate material. Considering the experimental results; CGI production has been successfully accomplished in the desired structure depending on the increase in the addition of the vermiculariser. It has been found that the number of grains increases with the amount of FeSi inoculate and that the vermiculated graphite can be produced at the targeted scale. Moreover, due to the addition of Cu the matrix structure has become ferrite+pearlitic instead of ferritic.
