Evolution of crystallite size, lattice parameter and internal strain in Al precipitates during high energy ball milling of partly amorphous Al87Ni8La5 alloy

“…The lattice parameter of the fcc-Al precipitates was determined by Rietveld analysis of the characteristic peak positionstaking into account the zero correction for the sample displacement, see where a Al = 4.050Å [17]and a Ni = 3.525 Å [18]denote the lattice parameters of pure Al and pure Ni, respectively.Based on the assumption that the lattice parameter is exclusively changed by the uptake of Ni,0.85% of Ni isdissolved in the fcc-Al precipitates after 1440 min of milling time. The uptake of La into the fcc-Al lattice would require a larger Ni concentration in the lattice to obtain the same change in the lattice parameter.According to Okamoto [19,20],both Ni and La arenotsoluble in fcc-Al.AlsoDan et al [21]reported aminor solubility of 0.01% of Ni in Al at 640 °C in a binary Al-Ni phase system.…”

Development of Biaxial Tensile Test System for <i>In-situ</i> Scanning Electron Microscope and Electron Backscatter Diffraction Analysis

“…[4][5][6] The n-value is controlled by grain size 7) or chemical composition. 8) Therefore, microstructure analyses by X-ray diffraction (XRD), [9][10][11] scanning electron microscope (SEM) [12][13][14] and electron backscatter diffraction…”

Nucleation and growth during recrystallization

“…In 1924, Wever 15 published the first pole figures on cold rolled aluminum and iron. In 1931, Burgers and Louwerse 16 have suggested that the recrystallization texture of aluminum single crystals was a result of oriented nucleation ("oriented nucleation theory").…”
