关键是你的lattice strain的定义? taoyulun 我的也是出现了5度的XRD变化,很大的变化我认为是掺杂引起的! zhaohaig 是衍射峰的偏移吗? wormma 根据峰的偏移计算应变。 liubin1984 5楼: Originally posted by zhaohaig at 2011-11-29 11:10:02: 是衍射峰的偏移吗? 可能是,但是我不清楚�, liubin1984 6楼...
Peak broadening in X-ray powder diffraction (XRD) profiles of LaNi 5-based alloys after hydriding and dehydriding processes was investigated in order to clarify the mechanism of formation of lattice strain in hydriding and dehydriding. The Rietveld method was used to evaluate the degree of peak ...
1 The in-plane strain and lattice rotation of polar convergent meron in the PTO/SSO film. (a) The atomic-resolved cross-sectional HAADF-STEM image of the trapezoidal domain. Yellow and red circles denote the Pb and Ti atom columns, respectively. Yellow arrows denote the directions of −δ...
the XRD intensities of (00l) peaks are very weak and broad, indicating severe lattice strain at thecaxis direction that prevents the re-insertion of Na+. Moreover, as evidenced by the disappearance of O3 (003), (006), (101), (108) and (110) peaks of the O3 phase, the O1 phase ...
Lattice strainNanostructured AA6005A alloy reinforced with 3 vol% of nano-size TiC particles (ranging in size from 20 to 30nm) of average crystallite size 55–65nm was successfully synthesized by high-energy ball milling (HEBM) process for 10h following a conventional powder metallurgy route. ...
Proper XRD analysis methods are suggested to determine the lattice parameter, solubility of minor elements, crystallite size and strain variance in the MA Al-Ti samples. Pure A1 is used as an internal standard to correct instrumental ... HS Kim,DS Suhr,GH Kim,... - 《Metals & Materials》...
The Ni(W) {111} solid solution strain evolution during a uniaxial tensile test is studied and compared to that of the pure Ni {111} phase by using the same in situ tensile tests combined with XRD. In addition, we analyzed the plastic and fracture behavior using in situ monitoring of the...
the distance measured with EXAFS is in good agreement with that measured with XRD but for the equiatomic NiCoFeCrPd alloy, the distance measured with EXAFS is obviously smaller (1.7%) than that from the XRD measurement, which suggests that there is a larger lattice strain in the NiCoFeCrPd ...
1) lattice strain 晶格应变1. The influence on Co lattice strain is not the same for different crystal structures of rare earth oxide. 用X-ray法研究了高能球磨制备Co-La2O3和Co-CeO2粉过程中Co粉的宏观应力与球磨时间的关系,两种不同晶型的稀土氧化物对Co粉的晶格应变影响不尽相同,掺La2O3的粉末...
