Abstract The mathematical model of the globular eutectic solidification in 2D was designed. Proposed model is based on the Cellular Automaton Finite Differences (CA-FD) calculation method. Model has been used for studies of the primary austenite and of globular eutectic grains growth during the ductile iron solidification in the thin wall casting. Model takes into account, among other things, non-uniform temperature distribution in the casting wall cross-section, kinetics of the austenite and graphite grains nucleation, and non-equilibrium nature of the interphase boundary migration. Calculation of eutectic saturation influence (Sc = 0.9 - 1.1) on microstructure (austenite and graphite fraction, density of austenite and graphite grains) and temperature curves in 2 mm wall ductile iron casting has been done.

Abstract The paper presents the results of investigations of the growth of protective coating on the surface of ductile iron casting during the hot-dip galvanizing treatment. Ductile iron of the EN-GJS-600-3 grade was melted and two moulds made by different technologies were poured to obtain castings with different surface roughness parameters. After the determination of surface roughness, the hot-dip galvanizing treatment was carried out. Based on the results of investigations, the effect of casting surface roughness on the kinetics of the zinc coating growth was evaluated. It was found that surface roughness exerts an important effect on the thickness of produced zinc coating.

Ductile Iron Casting

Mechanical properties of ductile iron casting are strongly inclined with metal matrix microstructure, graphite elements presence and impurities rate. Increasing in the number of graphite elements near to sphere shape (nodule), more superior mechanical properties will be realized. Automotive castings normally produced in mass production due to high demand; vertical moulding configuration is one of the best options for producing mass quantity automotive castings. This study aim to discover either the vertical moulding configuration will affects the nodularity properties distribution for different cavity position in the mold. In this study, ductile iron disc brake castings have been produced by in-mold Mg treatment using vertical parted molding method. Samples from different cavity position were taken and analyzed their nodularity distribution. Image processing computer procedure-Lieca was used to characterize the graphite morphology of the samples. The result shows that the different cavity position of vertical orientation disc brake casting produced dissimilar distribution of graphite. Higher position of cavity has higher nodule count and round graphite.
