本文综述了以钒油V-4Cr-4Ti为参考成分的钒合金的研究进展。研制了新型高纯度V-4Cr-4Ti锭及制品（nifs - heat）。合金纯度的提高，实际证明了在核聚变反应堆中使用后，回收利用作为一种处理方法的可行性。通过对各种不同杂质含量的大热合金和模型合金的比较，对V-4Cr-4Ti的物理冶金学和O、N、C油对合金低温、高温力学性能、焊接性能和低温辐照效果的影响的认识取得了重大进展。还讨论了其他微量杂质对某些性能的影响。综述了目前在表征V-4Cr-4Ti、改善其性能和探索先进钒合金方面所做的其他努力。讨论了今后研究中有待解决的问题。(C) 2002 Elsevier Science B.V.版权所有
This paper reviews recent progress in research on vanadium alloys with emphasis oil V-4Cr-4Ti as a reference composition. New high purity V-4Cr-4Ti ingots and products (NIFS-HEATs) were made. The improved purity of the alloys made a practical demonstration of enhanced feasibility of recycling as a method of handling after use in fusion reactors. Significant progress has been made in the understanding of physical metallurgy of V-4Cr-4Ti and effects of O, N and C oil the alloy properties such as low and high temperature mechanical properties, welding properties and low temperature irradiation effects, by means of including the comparison of various large heats and model alloys with different impurity levels. The effects of other trace impurities on some of the properties are also discussed. Other current efforts to characterize V-4Cr-4Ti, to improve its properties and to explore advanced vanadium alloys are reviewed. Issues remaining for the future investigations are discussed.
