以Ti-6.0wt.%Mn和Ti-8.1wt.%V为模型两相合金，以Ti-13.0wt.%Mn和Ti-14.8wt.%V为单相，研究了α相和β相交互作用对β钛合金拉伸和蠕变行为的影响。α-βTi-8.1V的β相由应力诱发的六方马氏体(α‘)形变，而单相的β相则发生滑移和孪晶，其化学成分与β相相同。在贝塔和α-贝塔钛锰合金中没有观察到应力诱发马氏体。这种行为是根据许多因素来模拟的，包括α和β相之间的弹性相互作用应力，α相和六方马氏体之间的共格，以及β相的稳定性。
The effects of alpha and beta phase interactions on the tensile and creep deformation behavior of beta titanium alloys was studied using Ti-6.0wt.%Mn and Ti-8.1wt.%V as the model two-phase alloys, and Ti-13.0wt.%Mn and Ti-14.8wt.%V as the single-phase beta alloys. The beta phase of alpha-beta Ti-8.1V deforms by stress-induced hexagonal martensite (alpha'), while slip and twinning occurs in the single-phase beta alloy with the same chemistry as the beta phase. No stress-induced martensite was observed in the beta or alpha-beta Ti-Mn alloys. This behavior is modeled in terms of a number of factors, including elastic interaction stresses between the alpha and beta phases, coherency between the alpha phase and hexagonal martensite, and beta phase stability.
