DEFINITION

Classification: 505/733

Rapid solidification (e.g., quenching, gas-atomizing, melt-spinning, roller-quenching):

(under subclass 725) Process in which a molten or melted superconducting material or superconducting precursor material is rapidly cooled or quenched.

(1) Note. For purposes of this subclass, the use of quenching without indication of speed will be sufficient for placement. Moreover, the use of the techniques of gas atomization, melt-spinning or roller-quenching will be considered rapid solidification.
