Abstract
A Continuous Ultra-Rapid Annealing (CURA) method for producing a nanocrystalline alloy is provided. The method includes placing amorphous ribbons on a first reel, preheating a Cu wheel to a temperature of about 750° K to about 800° K, and unwinding the amorphous ribbons from the first reel to a second reel. The methods include directly contacting the amorphous ribbons between the first reel and the second reel with the Cu wheel for a length of time and under tension to produce the nanocrystalline alloy. The methods include winding the nanocrystalline alloy on the second reel.
