| Outline of Final Research Achievements |
The development of thin walled spheroidal graphite cast iron with reduced rare earth was aimed. We have focused on graphite spheroidizer contained rare earths be used during casting. Chill of research in thin walled, effect of casting defects on the fatigue strength, the impact test by test specimen was cut out from the entity production. Resulting in, even if the common rare earth to the graphite spheroidizer is contained 2.0% was reduced to 0.3%, it was possible to suppress deterioration in quality.
