| 摘 要： | 1 样品制备样品分两组:第一组研究添加 Y 的不同含量对合金塑性的影响,选用0.1,0.2,0.3wt%添加量,在预抽真空为10~(-1)mmHg 后充以工业氩气(纯度为98%)保护下,在水冷铜坩埚内反复熔炼成小钮扣锭.第二组样品是在真空度为10~(-4)mmHg 的自耗电弧炉中熔炼而成,一种添加0.3wt%Y,另一种是纯 NbTi50wt%.熔炼电压30kV,电流密度5A/mm~2.所用原料为标准国产 NbTi50wt%棒和纯度为99.95%的块状 Y.所有样品都经过1350℃、5小时均匀化热处理,950℃、20min 固溶处理,热锻,水淬(高于800℃),然后作拉伸试验.

| Abstract: | The author did severl experiments to examine the effect of yttriom addition on the plasticity of the national NbTi50wt% superconducting alloys at the room temperature,It is found that Yttrium can obviously improve the plasticity of this alloy through the study of the tensile properties.The alloy has the best plasticity with an addition of 0,2wt%Yttrium.Chemical analys- es show that yttrium does not reduce total interstitial amount in two differe- nt smelting conditions. |
