Proposal of Inspection Method for Shrinkage Cavities in Spheroidal Graphite Cast Iron by Electromagnetic Force Vibration Using Differential Vibration Measurement

Spheroidal graphite cast iron is often used for machine parts that require high strength. A shrinkage cavity may be generated inside the cast iron during the manufacturing process. If there is a shrinkage cavity in the cast iron, the strength of the cast iron is significantly reduced. In this articl...
