2008年10月1日 · Intermetallics and phase transformations of the zirconium-based alloy, Zr-1.0Sn-0.3Nb-0.3Fe-0.1Cr, were investigated by conventional X-ray diffraction (XRD), differential scanning calorimetry (DSC), and dilation measurement. Three types of precipitates, namely, (ZrNb) 2 Fe, Zr (CrFe) 2, and Zr 3 Fe, were detected by XRD.

2019年4月1日 · We have investigated proton irradiation induced Nb redistribution in Zr-xNb alloy (x = 0.4, 0.5, 1.0) by using Scanning Transmission Electron Microscopy (STEM) and Atom Probe Tomography (APT). Initially without an irradiation effect, the Zr matrix only contains βNb and native Laves phase native precipitates.

2022年7月1日 · XRD experiments were performed to investigate the radiation-induced structural evolution of C-, Si-, and Cu-irradiated Zr/Nb with different layer thicknesses (6 nm, 27 nm, 96 nm).

In Figure 4, the X-ray diffraction patterns of the ZrNb alloy processed with PEO in the electrolyte containing Ca, P, KOH, and Cu nanoparticles are shown. The XRD pattern of the unprocessed...

3 天之前 · The AlTiZrNbMo high-entropy alloy exhibits superior corrosion resistance due to a wide and stable passivation zone. Larger radii Nb prompts uphill diffusion of Ti/Al atoms to form a stable Al2O3 ...

结果表明,每条曲线的斜率略有不同, 这表明Nb含量会影响ZrNb 试样的弹性模量。 随着Nb 含量的提高,曲线斜率有略微增加, 当Nb 含量为2.5%( 质量分数) 时,应力− 应变曲线的斜率最小, 这说明Nb含量的增加将提高合金的弹性模量, 低Nb 含量的ZrNb试样更容易变形。

Subsequently, the microstrueture of different compo- sitions of Zr-Nb alloys was validated by X-ray diffraction （XRD） , scanning electron microscopy（SEM） , transmission electron micros- copy （TEM） etc.

2023年6月21日 · We extract the Zr concentrations as a function of depth (Figure 4c) in the β-ZrNb part of ZrNb (CO), after excluding the ZrO 2 and NbC signals. The profile reveals an inhomogeneous distribution, with a concentration spike with a small depth of ≈ 10 nm, followed by a rapid decline reaching 10 –30 at.%

利用团簇成分式方法设计了 [Zr-Zr 14] (Zr, Nb) 3 系列二元合金，进而采用Ti替代部分Zr形成三元合金；采用真空铜模吸铸快冷技术制备合金棒材，利用XRD、OM、TEM等对其进行微观组织表征和力学性能测试。

Good ductility, low magnetic susceptibility, and tunable Young's modulus are highly desirable properties for materials usage as spinal fixation rods. In this study, the effects of niobium content...
