Method for improving current carrying capacity of second-generation high-temperature superconducting tape
A method for improving current carrying capacity of a second-generation high-temperature superconducting tape, which includes: stretching the second-generation high-temperature superconducting tape in a high-temperature environment, and carrying out an oxygenation heat treatment on the stretched second-generation high-temperature superconducting tape The atmosphere of the high-temperature environment is oxygen, or an inert gas, or a mixture thereof, and a temperature of the high-temperature environment is 450-650° C.; and a strain for stretching ranges from 0.1% to 1%, and a time for stretching ranges from 1 minute to 100 hours. The method of the present invention is a post-processing technique for the second-generation high-temperature superconducting tape with a simple treatment process and a controllable result, and by stretching, current carrying capacity of the superconducting tape is improved and anisotropy of superconductivity is reduced.
