具有应力诱导纳米级{110}、{021}型复合孪晶或90°旋转孪晶的完全转变的α”马氏体已经在传统β型钛合金中通过实验探索并明确表征，这些合金通常通过淬火进行部分马氏体转变[β晶粒部分转变为具有内部(111)孪晶的α”晶粒]。这种新观察到的孪生现象，与基于 Bilby 和 Crocker 变形孪生理论的预测相符。 R.苏克。 288, 241 (1965)]，可以帮助解释变形机制并帮助先进材料的未来发展。
A fully transformed α″ martensite with stress-induced nanoscale {110}, {021}-type compound twin or a 90° rotation twin has been experimentally explored and unambiguously characterized in traditional β-type Ti alloys, which usually undergo a partial martensitic transformation [a β grain partially transformed into α″ with internal (111) twin] by quenching. This newly observed twinning, which matches with the predication based on the deformation twinning theory of Bilby and Crocker [Proc. R. Soc. 288, 241 (1965)], can help to explain the deformation mechanism and aid future development of advanced materials.
