“…The changes of the XRF parameters for elements in alloys can be explained as a result of changes in the valance electronic configurations or charge transfer effect. Recently, several researches have been carried out the alloying effect on various parameters such as various physical properties of 3d transition metals alloys (Chattopadhyay & Manna, 2002;Chen et al, 2004Chen et al, , 2009Diercks & Loomis, 1986;Evtikhin, Lyublinski, Vertkov, Votinov, & Dedyurin, 2002;Kim, Kim, Choi, & Jeong, 2006, 2008Lai, Chen, Tsai, & Ding, 2003;Sadrnezhaad & Selahi, 2004;Santos, de Castro, Ishikawa, & Ticianelli, 2007;Takahashi, Ohnuki, Kinoshita, & Nakahigashi, 1991;Wang & Wang, 2009;Wei, Changlong, Tao, & Xiaohua, 2007;Yao, Li, Wee, Chai, & Pan, 2001). And also, alloying effect on K XRF crosssection and K-shell fluorescence yield for Cr, Ni, Al elements in Cr x Ni 1-x and Cr x Al 1-x alloys (Büyükkasap, 1998a, b) and for Ni in NieSi alloys (Kalayci et al, 2005) have been reported.…”

The samples were excited by 22.69 keV X-rays from a 10 mCi Cd-109 radioactive point source and K X rays emitted by samples were counted by a high resolution Si(Li) solid-state detector coupled to a 4 K multichannel analyzer (MCA). The alloying effects on the X-ray fluorescence (XRF) parameters of Ti-Ni shape memory alloys (SMAs) were investigated. It is clearly observed that alloying effect causes to change in K shell XRF parameter values in Ti-Ni based SMAs for different compositions of x. Also, the present investigation makes it possible to perform reliable interpretation of experimental s Ka , s Kb and u K values for Ti and Ni in SMAs and can also provide quantitative information about the changes of K shell X-ray fluorescence cross sections and fluorescence yields of these metals with alloy composition.

“…The new type of zirconium alloy with the composition of Zr-1.1Nb-1.51Fe-0.26Cu-0.72Ni is developed on the basis of N36 zirconium alloy by means of adding the chemical content of elemental Ni, Fe, and Cu, and eliminating elemental Sn. Elemental Cu and Fe can increase mechanical strength and corrosion resistance [ 17 ]. Elemental Nb can enhance corrosion and irradiation-induced swelling resistance [ 17 , 18 , 19 ].…”

In Situ TEM Study of Microstructure Evolution of Zr-Nb-Fe Alloy Irradiated by 800 keV Kr2+ Ions

The microstructure evolution of Zr-1.1Nb-1.51Fe-0.26Cu-0.72Ni zirconium alloy, irradiated by 800 keV Kr2+ ions at 585 K using the IVEM-Tandem Facility at Argonne National Laboratory, was observed by in situ transmission electron microscopy. A number of β-Nb precipitates with a body-centered cubic (BCC) structure were distributed in the as-received zirconium alloy with micrometer-size grains. Kr2+ ion irradiation induced the growth of β-Nb precipitates, which could be attributed to the segregation of the dissolved niobium atoms in the zirconium lattice and the migration to the existing precipitates. The size of precipitates was increased with increasing Kr2+ ion fluence. During Kr2+ iron irradiation, the zirconium crystals without Nb precipitates tended to transform to the nanocrystals, which was not observed in the zirconium crystals with Nb nanoparticles. The existing Nb nanoparticles were the key factor that constrained the nanocrystallization of zirconium crystals. The thickness of the formed Zr-nanocrystal layer was about 300 nm, which was consistent with the depth of Kr2+ iron irradiation. The mechanism of the precipitate growth and the formation of zirconium nanocrystal was analyzed and discussed.

The Zr-Nb alloys were modified by doping of Mo as a minor alloying element to seek for the nuclear fuel cladding materials with better characteristics. The effects of Mo on microstructural evolution and mechanical properties in Zr-Nb alloys were systematically investigated and elucidated. Results showed that the martensitic microstructure, a mixture of lath martensites and lens martensites with internal twins, was observed in the alloys quenched from β-phase. Width of the lath martensite reduced with the increasing Mo concentration, and the volume fraction of lens martensite increased with increase in the Mo concentration. After final annealing, a new kind of precipitate, namely β-(Nb, Mo, Zr), was identified in the Mo-containing alloys. It was also found that Mo reduced the growth of the precipitates but increased their number density. Furthermore, Mo addition retarded the recrystallization process strongly and reduced the grain size significantly. In terms of the mechanical properties, Mo addition enhanced the yield strength and the ultimate tensile strength at room temperature, however decreased the ductility. The grain size strengthening was presumed as the greatest contributor in this system.
