Dr. Kathy lectures at Michigan Tech University

For the past 20 years, Dr. Kathy Hayrynen has spent a week with the MTU Fundamentals of Metal Casting class discussing ductile iron and ADI.  The 2021 event was held during the week of October 25th.  Lectures on the production of ductile iron and heat treatment of ductile iron with a focus on austempering were shared with the students.  Laboratory activities focused on the process of converting a steel weldment to an Austempered Ductile Iron casting.
