Rapid solidification using melt spinning was through collaboration with the Advanced Magnetic Group at Defence Metallurgical Research Laboratory (Dr. Bhaskar Majumdar and Dr. M. Manivel Raja). Undercooling provides a way to rapidly solidify alloys but at low cooling rates. Undercooling experiments are done in our own lab.
