| Abstract: | Ductile Iron castings with section thickness 60mm, 70mm & 80mm were
produced using manufacturing process in which the chemical composition was adjusted
to guarantee the formation of spheroidal graphite during solidification. Simultaneously
other parameters like carbon equivalent, tapping temperature, inoculation and magnesium
residuals were monitored. Microstructure and its constituents of these thick wall castings
were characterized using an image analyzer. Matrix structure and graphite forms were
investigated as a function of section thickness. Pearlite content, nodule count and
nodularity decreases with increasing section thickness where as nodule size increases. |
