Sep 10 2019 · Abstract Ferritic spheroidal graphite cast iron SGI materials have a remarkable technical potential and economic impact in modern industry These features are closely related to the question of how the cast materials can be produced without structural defects and graphite degenerations such as for example chunky graphite

The graphite within ductile iron occurs as spheroids so it is sometimes referred to as spheroidal graphite Similarly the term nodular iron stems from the fact that the carbon contained in ductile iron is held in the form of nodules

Ductile iron also known as ductile cast iron nodular cast iron spheroidal graphite iron spheroidal graphite cast iron and SG iron is a type of graphiterich cast iron discovered in 1943 by Keith Millis While most varieties of cast iron are weak in tension and brittle ductile iron has much more impact and fatigue resistance due to its nodular graphite inclusions

Density The generally accepted value for the room temperature density of Ductile Iron is 71 gCM 3 Density is affected primarily by the percentage of graphitized carbon with densities varying from 68 gCM 3 to 74 gCM 3 for high carbon ferritic and low carbon pearlitic irons respectively

The rate equation of anodic dissolution reaction of spheroidal graphite cast iron in sulfuric acid solutions at 298 K has been studied The cast irons have different areas of pearlite The anodic Tafel slope of 0043 V decade−1 and the reaction order with respect to the hydroxyl ion activity of 1 are obtained by the linear potential sweep technique
