Change in the lattice parameter of aluminum under the influence of rapid quenching from the liquid stateMeasurements of broadening of X-ray diffraction peaks were made for splat cooled pure aluminium samples, and some splat cooled aluminium-tin and aluminium-nickel solid solutions. A Fourier analysis...

A parameter-free, self-consistent method for calculating the gradient of the total energy (i.e., forces on atoms) of point defects in semiconductors is described. It is shown that under two conditions, (i) the pseudopotential approach and (ii) the inclusion of basis-set derivatives, the Hel...
2) lattice parameter 点阵常数 1. The lattice parameter for Cu is 0. 结果表明,机械合金化过程中Cu粉和C粉形成了层状复合粉末;随着球磨时间的增加,C的衍射峰逐渐消失,Cu的衍射峰逐渐宽化,并且位置发生偏移;球磨24h后,C原子固溶到Cu中,Cu的点阵常数达到0。 2. A neural network method is proposed to...
For example, Cao et al. [13] introduced a shape parameter in the cross section of the strut that resulted in an increase of the compressive modulus and of the initial yield strength by 79% and 55%, respectively. Some non-isotropic geometries, characterized by struts placed only in certain ...
The increasing thermal conductivity is further supported by the temperature dependence of the Gruneisen parameter (Fig. 4c), which shows a roughly inverse relationship to thermal conductivity as illustrated in Fig. 4d. From 725 K to 850 K, both the increase in the TO mode frequencies and ...
An X-ray scattering camera is described in which precise measurements of the lattice parameter is carried out at three temperatures.The camera is an improved modification of the Seeman-Bohlin X-ray camera in which two mobile shields are used to record the diffraction lines according to a predeter...
38. Although these studies provide valuable guidance for the predictive synthesis of layered oxides, most of them have focused on examining the impact of structural characteristics during the heating/holding process, such as phase impurity, lattice parameter, crystallite size, Li–TM bond length, and...
1.The crystal lattice constant is an important parameter of the crystal and it changes extremely slightly.晶体的点阵常数是晶体的重要参数,它的改变是极细微的。 2.In this paper,we apply X ray diffractometer method to determine the crystal space lattice constant of spectrum pure metallic copper Cu ...
