2024年2月1日 · The XRD results depicting the fracture surfaces of the Zr-4 joints under bonding temperatures of 740–800 °C for 30 min are displayed in Fig. 11. The diffraction peaks were relatively similar and consisted of β-Nb and β-Zr phases without α-Zr, which corresponded to the phases in Region I.

2018年2月14日 · The influences of Zr4+ doping modification on the microstructure and micromorphology of Li1.20 [Mn0.52Ni0.20Co0.08]O2 cathode materials were studied intensively by the combinations of XRD, SEM...

2024年10月8日 · Crystal structure and phase compositions were observed using X–ray diffraction (XRD) with a Cu anode material, operated by PANalytical, EMPYREAN, scanning from 20 to 80 degrees at 25 °C.

2023年12月1日 · A series of Zr 4+ doped spinel ferrite, Mg 1-x Fe 2 O 4: xZr (x = 0, 0.25, 0.5, 0.75, 1, 1.25 and 1.5 mol %), were synthesized using the solid-state reaction method. The XRD patterns analysis and Rietveld refinement revealed the formation of single-phase cubic spinel structure with Fd-3m (227) space group.

2024年5月7日 · In the present work, Zr-4 alloy was chosen as a model material to study the effect of β-quenching on oxidation resistance and relevant mechanisms. Zr-4 sheets were quenched from β phase temperature region and subsequently oxidized for 4-16 hrs in air. The β-quenched Zr-4 exhibited a better oxidation resistance than its recrystallized counterpart.

2024年4月1日 · As z value increases, the XRD peaks of the main phase and the second phase shift towards lower degrees together, indicating that the cell volume increases. It confirms that Zr 4+ and Hf 4+ with larger ionic radii continuously substitute for Ti 4+ with a smaller ionic radius both in the main phase and the second phase.

In this study, antibacterial activity of a zirconium (IV)–Schiff base ligand [Schiff base = N,N′-bis (3-salicylidenaminopropyl)amine] was examined via the paper disk diffusion method against...

X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and high resolution transmission electron microscopy (HRTEM) techniques were used to investigate the existing states and doping mechanism of dopants as well as the phase transition of the Zr …

采用XRD, OM, BSE, SEM和显微硬度计等手段研究了氘含量对Zr-4合金显微组织及力学性能的影响. 结果表明, 随着氘含量 (质量分数)从1.35%增加到2.21%, 氘化物数量增加, 其形态及分布也发生了显著变化: 在1.35%时, 主要以晶内针状氘化物析出为主; 随着氘含量增加, 晶界块状氘化物快速增长; 当氘含量进一步增加至2.21%时, 晶界块状氘化物开始相互衔接, 并逐渐向晶内生长. 在氘含量较高的样品表层, 有一定厚度的氘化物层形成, 且层内出现微裂纹. 所形成的氘化物以δ-氘化物为主, …
