In hypereutectic nodular cast irons, primary precipitation of graphite may lead to graphite flotation in thick section castings Graphite degeneracy such as so-called exploded graphite is then often associated with this flotation phenomenon and it appears as precipitates where the nodular form is replaced by star-like or flower-like shape It has been reported that exploded graphite develops ....
Jan 06, 2010 0183 32 Graphite flotation does not effect tensile poperti It can reduce fatigue resistance marginally but i doubt it would cause a failure there maybe other factors that have caused this If it has then your design criteria is too tight This should be reviewed and fully investigated and understood The main problem with graphite flotation is a ....
