IPC: C22F1/00
Filed: 1991-11-12
Abstract: PURPOSE:To improve the high magnetic-field characteristics while minimizing the degradation of the characteristics due to coiling, by conducting a first heat treatment before cooling at a high temperature and a for a short time period, and then conducting a second heat treatment at a low temperature and for a long period of time. CONSTITUTION:The manufacturing method comprises the step of causing a wire, which is prepared by composing raw material members for an Nb-based compound superconductive wire, to be subjected to a first heat treatment, the step of causing the wire after the first heat treatment to be worked into a specified configuration, and the step of causing the wire of such a specified configuration to be subjected to a second heat treatment which is conducted at a temperature lower than that, and for a time period longer than that, in the first heat treatment. In this case, by conducting the first heat treatment under conditions of high- temperature/short time period prior to working of the wire into a specified configuration, the wire is coiled in a condition wherein Nb3Al with excellent high magnetic-field characteristics is likely to be easily produced. After performance of the first heat treatment and subsequent working of the wire into a specified configuration such as a coil, the second low-temperature/ long-period heat treatment is conducted to improve the high magnetic-field characteristics. This minimizes the degradation of the characteristics due to working such as coiling.
