所得结果可用于从生成最佳Nb-Sn相组成方面来优化A15相成相热处理制度. 本研究得出的结论是,对于像ITER使用的高场磁体超导线来说,鉴于其需要在较高磁场下有高的临界电流密度,就需要将超导线的热处理温度适当提高一些. 本实验所用Nb3Sn超导线材的最适宜热处理制度为:675°C/128小时,这样可以得到最佳不可逆温度特性,即最佳的A15相组成.","authors":[{"authorName":"张超武","id":"be617ec2-297c-4537-a8ad-a0e305a7e239","originalAuthorName":"张超武"},{"authorName":"","id":"de263a79-aec4-485b-93fe-6eb935b2234f","originalAuthorName":""},{"authorName":"周廉","id":"3e62b47d-8f91-41ec-9290-00392d45ed79","originalAuthorName":"周廉"},{"authorName":"唐先德","id":"11ebfa21-1046-4ec1-a1b3-4a22cb361fd5","originalAuthorName":"唐先德"},{"authorName":"","id":"fb55ca77-072e-4499-84c4-0a1091c2432e","originalAuthorName":""},{"authorName":"张平祥","id":"e67ab32a-1283-401a-8d2e-c5fbe83d9fb1","originalAuthorName":"张平祥"},{"authorName":"卢亚峰","id":"9cbde4f1-1345-4f79-871a-9005f9cb64b4","originalAuthorName":"卢亚峰"}],"doi":"10.3969/j.issn.1000-3258.2006.04.002","fpage":"311","id":"9f600dc6-b5e3-4b45-8b68-ccf4fa91bb75","issue":"4","journal":{"abbrevTitle":"DWWLXB","coverImgSrc":"journal/img/cover/DWWLXB.jpg","id":"19","issnPpub":"1000-3258","publisherId":"DWWLXB","title":"低温物理学报
