The deposit was in face-centered cubic structure without obvious crystal face preferred orientation. Its lattice distanced and lattice parameter a were larger than those of standard copper powder, which indicated that the obtained deposit was still present internal stress and defects. 铜镀层为面心立方结构,没有明显的晶面择优取向现象,镀层结构的晶面间距d和晶胞参数a与标准Cu粉末的相比均较大,说明铜镀层仍存在应力和缺陷。
Orientation stability during uniaxial tension of face-centered cubic ( FCC) metal sheets is predicted using a rate-sensitive crystal plasticity model. 采用速率敏感晶体塑性理论,预测了面心立方金属板材单轴拉伸过程中主要理想取向的稳定性。
It was found that a cobalt-based solid solution with a face-centered cubic crystal structure is presented accompanied by the secondary phase M_7C_3 with a hexagonal crystal structure in the cobalt-based alloy coating. 结果表明,堆焊合金层主要是由面心立方的γ(Co)和六方结构的M7C3构成,并且在钴基固溶体中存在着许多堆垛层错。
The results show that the adsorption ( or desorption) process of hydrogen at electrodes of face-centered cubic metal occurs in several stages owing to the characteristics of the crystal surface, and corresponding current peaks appear on the I-η curves. 结果表明,氢在面心立方金属一类的电极上,吸(脱)附过程由于晶面特性而分阶段进行,在I-η曲线上出现几个相应的电流峰。
The binding energy of face-centered cubic lattice and hexagonal lattice for C_ ( 60) crystal was calculated by using the analytic interaction potential, the stability of different lattice was discussed and the reason why C_ ( 60) is general face-centered cubic lattice was explained. 用该表达式计算了C(60)分别为面心立方和六方晶格时晶体的结合能,讨论了不同晶格的稳定性问题,解释了C(60)晶体一般是面心立方的原因。
The quantitative relationship between quasi-particle geometry model and face-centered cubic crystal lattice has been proposed. 并推导出该拟质点几何模型与面心立方晶胞之间的定量数值关系。
