Nb
1.
The effect of niobium on high temperature creep performance of nickel based alloy was investigated.
研究了Nb对Ni基合金高温蠕变性能的影响,认为Nb主要是通过增强第二组γ′相沉淀强化,γ相固溶强化,晶界M23C6 呈链状分布,而使Ni基合金抗蠕变性能提高。
2.
TMCP(Thermo-Mechanical Controlled Process) tests were carried out,and the microstructure and stretch-flange-formability of low carbon FB steels microalloyed with niobium were analyzed.
通过TMCP试验,研究了不同Nb含量低碳FB钢的微观组织和扩孔性能。
3.
The influences of microalloy element niobium (Nb) on the stacking fault energy and mechanical properties of Fe-22Mn-0.
研究了微合金元素Nb对Fe-22Mn-0。
5) uranium-niobium
U-Nb
6) Beta-niobium(β-Nb)
