Abstract
A method to produce cast iron articles with various graphite morphologies is disclosed that provides cast iron with tailored properties at different locations of the article. Flake graphite morphology is preferably created at locations requiring excellent thermal conductivity or lubricity. Spheroidal graphite morphology is preferably created at locations requiring excellent strength or mechanical fatigue life. These methods may be particularly valuable for the production of heavy duty diesel engine components.
