production cross-sections, Kβ/Kα, KLM/Kα and KMM/Kβ RAE intensity ratios of Ni and σKα,σKβ1,2 production cross-sections, Kβ1,3/Kα, Kβ2,4/Kα, Kβ2,4/Kβ1,3, KLM/Kα and KMM/Kβ RAE intensity ratios of Mo have been measured in pure metals and in superalloy specimens. The samples were excited by 59.5 keV γ-rays from a 241Am annular radioactive source. K X-rays emitted by samples were counted by an Ultra-LEGe detector
在这项研究中,σ ķ α,β σKα,β生产的横截面,ķ β / ķ α,KLM / ķ α和KMM / ķ β Ni和σKα,σKβ1,2的RAE强度比生产的横截面,ķ β1 ,3 / ķ α,ķ β2,4 / ķ α,ķ β2,4 / ķ β1,3,KLM / ķ α和KMM / ķ βMo的RAE强度比已在纯金属和高温合金样品中进行了测量。样品由241 Am环形放射源的59.5 keVγ射线激发。用Ultra-LEGe检测器对样品发出的K X射线进行计数,分辨率为5.9 keV,分辨率为150 eV。研究了合金化对镍和钼的荧光参数,相结构和腐蚀行为的影响。高温合金中Ni和Mo的X射线荧光参数表明,与纯金属相比,存在显着差异。这些差异归因于超合金中价电子的重组和/或电荷转移现象。
