The structure and energy associated with interfaces between the BCC and HCP lattices (β and α phase, respectively) in titanium alloys with commonly used β stabilizers were analyzed. For this purpose, the crystallographic structure of the matching facets of broad, side and end faces was described using misfit dislocations and structural ledges which compensate the mismatch in atomic spacing of the α and β phases. The effect of the β/α transformation temperature due to various concentration of β stabilizers on periodicity of misfit dislocations and structural ledges was estimated. The van der Merwe approach was used to calculate energy of different matching facets. An increase in the percentage of β-stabilizing elements was found to result in a decrease in the lattice-parameter ratio (a_β/a_α) and an increase in the energy of all faces. The dependence of the interface energy on the a_β/a_α ratio was for the first time quantified, and insight into the preferred shape of α-phase precipitates was obtained.

分析了具有常用β稳定剂的钛合金中BCC和HCP晶格（分别为β和α相）之间的界面相关的结构和能量。为此，使用失配位错和结构壁架来描述宽，侧面和端面的匹配面的晶体学结构，这些结构和壁架可以补偿α和β相原子间距的失配。β / α的不同浓度对β / α转变温度的影响。估计了错位错位和结构壁架周期性的稳定剂。van der Merwe方法用于计算不同匹配面的能量。在的比例的增加β -stabilizing元件被发现导致在晶格参数比的降低（一个_β /一_α在所有面的能量）和增大。界面能量对的依赖性一个_β /一个_α比为首次定量，洞察的优选形状α获得相沉淀物。
