Ductile Iron Data - Section 3 - Part 1

The increasing use of Ductile Iron components with as-cast surfaces places an increased importance on the elimination of surface defects for appliions requiring optimum fatigue strength. The reduction of dross-related surface defects through the use of filters in the mold filling system can result in a 25 per cent increase in fatigue life, as shown in Figure 3.31 .

Thermal Analysis of Ductile Iron Casting | IntechOpen

2017/4/10· Pure metals solidify with a solidifiion front that is very well defined and a clearly delineated solid-liquid interface. Ductile cast iron solidifiion is characterised by a very thin solidified skin and appearance of different phases. The outer skin is formed being very thin in ductile iron; the expansion occurs due to graphite nucleation into the casting forces to the mould walls. With

Effect of temperature on ausferritic nodular cast iron microstructure.

Appliion of Surface Layer Inoculation Processes to …

Modern cast iron grades of solid solution-strengthened ductile cast iron were incorporated into the European Standard EN 1563 in 2012. These are primarily characterized by their elevated silicon content, ranging from 3.2 to 4.3wt.% Si. Björkegren et al.1 showed that an increased silicon content leads to a fully ferritic matrix, which results in both improved machinability and very good static
