摘要:

研究了压力对钛六方密排结构的影响。平衡结构的晶格参数的吉布斯自由能,使用外延贝恩路径方法确定。当这个过程被重复几个压力,晶格参数上的压力的效果被揭示。计算的晶格参数与实验和理论结果吻合较好。利用密度泛函理论研究了压力对基态电导率和电阻率等电子结构参数的影响。

英文摘要:

The effect of pressure on the hexagonal close-packed structure of titanium is investigated. The lattice parameters of the equilibrium structure were determined in terms of the Gibbs free energy using the Epitaxial Bain Path method. When this process was repeated for several pressures, the effect of pressure on the lattice parameters was revealed. The calculated lattice parameters were in good agreement with the experimental and theoretical results. The effects of pressure on parameters depending on the electronic structure such as conductivity and resistivity in the ground state were also investigated up to 30 GPa using density functional theory.
