Prof. Johnson has expertise in levitation zone melting, in which induction power heats, lifts, and constrains the liquid zone during material purification. Electromagnetic, containerless confinement of the liquid zone removes the thermodynamic limitations imposed when using a crucible. Dr. Johnson’s group works on development and processing of high-temperature structural materials, phase diagram development of new metal alloys, and understanding defect formation during solidification.
Current research projects:
(E= experimental, M = modeling, P = includes industrial plant data)
• Alloy variations on mushy-zone reactions & defect formation (E, M)
Selected past research projects
(E= experimental, M = modeling, P = includes industrial plant data)
• Boron segregation and related hot shortness in continuously cast steel (E, M)
