"The mold coating and mold matrix have a tremendous effect on the thermal fatigue and mechanical fracture of continuously cast gray iron permanent mold inserts. The following research was completed to begin a study into the effects of mold geometry and mold coating on thermal fatigue.
The first part of the thesis describes the instrumentation and procedures for the experimentation. These procedures establish a repeatable method for obtaining data that relates mold coating, mold geometry, thermal fatigue, and mechanical cracking.
The second part involves an analysis of ferritic and pearlitic inserts. The impact of insert matrix and mold coating was studied with respect to the number of casting runs and the total number of castings that resulted in crack initiation, crack growth, and insert failure.
The last part provides a metallographic examination of crack initiation and growth mechanisms, including the effects of mold coating and mold matrix"--Abstract, page iv.
