在许多变形沉淀硬化镍基合金中，Nb被认为是一种重要的合金元素。本文的目的是研究Nb在这些合金中的作用，并描述由于它在变形高温合金中的夹杂而获得的性能。除了技术文献中描述的Nb的一般合金化特性外，还将研究Nb在X-750、740、706、725和718合金中的具体贡献。研究了Nb在微观结构中所起的作用以及由此产生的微结构对某些性能的影响。
Niobium is recognized as an important alloying element in a number of wrought precipitation-hardened nickel-base alloys. It is the purpose of this paper to examine the role that niobium plays in these alloys and describe the properties that are achieved as a result of its inclusion in wrought superalloys. In addition to the general alloying characteristics of niobium as described in the technical literature, the specific contribution of niobium in the alloys X-750, 740, 706, 725 and 718 will be examined. Niobium is examined for the role it plays microstructurally and the impact of the resulting microstructure on certain properties.
