为了改善聚变堆用钒合金的辐照脆化，在钒合金中加入钇（Y）以减少间隙氧杂质。但是，由于Y能将固溶体中的氧氧化，而氧是钒合金中的强硬化剂，因此Y的加入也会降低钒合金的高温强度。在这项研究中，Y的添加量和氧含量对力学性能的影响进行了研究，从高温强度和低温塑性的观点。Y的加入可缓和氧杂质引起的硬化和脆化，使合金的高温强度保持在可接受的水平。
Abstract In order to improve irradiation embrittlement of vanadium alloys for fusion reactors, yttrium (Y) has been added reducing the interstitial oxygen impurity. However Y addition can also degrade high-temperature strength, because Y could scavenge oxygen in solid solution, which is a strong hardening agent in vanadium alloys. In this study, the effect of Y addition and oxygen level on the mechanical properties was investigated from the view points of both the high-temperature strength and low temperature ductility. Y addition was suggested to moderate the hardening and embrittlement induced by oxygen impurity sustaining the high-temperature strength within an acceptable level.
