SUPERCONDUCTING WIRE, SUPERCONDUCTING STRANDED WIRE WITH USE THEREOF AND METHOD TO MANUFACTURE THEREOF

摘要

FIELD: chemistry; electric wire. ^ SUBSTANCE: material in the form of oxide superconducting wire, which comprises oxide superconducting part and metal coating thereon, distinguishing itself by the fact that the above metal coating material during stress-strain relationship test features relative rupture strain of 30% or more. ^ EFFECT: material in the form of superconducting wire features high critical current density and is less susceptible to vertical cracking or breaking during manufacture. ^ 14 cl, 3 dwg, 1 tbl, 10 ex
