Abstract–In the dynamic theory, the formation of twin martensite crystals is the result of a coordinated propagation of relatively long-wave (\(\ell \)-waves) and short-wave (s-waves) displacements. The matching condition is analyzed for the γ–α martensitic transformation in iron-based alloys, taking into account the quasi-longitudinalness of the \(\ell \)-wave carrying compression deformation. It has been shown for the first time that the previously established single-crystal effect of part of the crystals of thin-plate martensite, which arises upon cooling under the action of a strong magnetic field, can naturally be interpreted as a consequence of the formation of a degenerate structure of transformation twins.

强磁场引发的相变孪晶的简并结构和部分薄板马氏体的单晶性

摘要–在动力学理论中，双马氏体晶体的形成是相对长波（\（\ ell \） -波）和短波（s -wave）位移协调传播的结果。考虑到携带压缩变形的\（\ ell \）波的准纵向，分析了铁基合金中γ-α马氏体相变的匹配条件。首次表明，在强磁场作用下冷却时产生的薄板马氏体晶体的先前建立的单晶效应自然可以解释为形成的结果。变形双胞胎的简并结构。
