项目摘要
Dependence of the phonon dispersion relation on the uniaxial stress of the transverse acoustic lattice waves, TA mode, both in the parent phase(<beta>_1) and in the martensitic phases (<gamma>'_1,<beta>''_1 and <alpha>'_1)of Cu-Al-Ni alloys were measured. The phonon dispersion relation in the martensite <gamma>'_1 was independent of the uniaxial stress up to 275 MPa. Furthermore, the phonon dispersion relations in the martensites <beta>''_1 and <alpha>'_1, which were induced by the uniaxial stress from the martensite <gamma>'_1, were very similar to that in <gamma>'_1. The phonon dispersion relation in <gamma>'_1 softened slightly by heating from 10 K to A_s. By applying uniaxial stress, the phonon dispersion curve in the parent phase (<beta>_1) softened slightly around q values of (2/3)q_<max> and of the Brillouin zone boundary.The martensitic transformation is interpreted as a condensation process of solitons instead of phonons. A twin boundary in the martensitic phase is a soliton. The asustenitic phase at sufficiently high temperature consists of dynamic solitons. A finite bias field is required to stabilize dynamic solitons in the austenite. The premartensitic structure consists of solitons stabilized by the bias field associated with the composition fluctuation. The martensitic phase consists of the solitons stabilized adiabatically by the bias field associated with the martensitic transformation itself.
测量了 Cu-Al-Ni 合金母相 (<beta>_1) 和马氏体相 (<gamma>'_1、<beta>''_1 和 <alpha>'_1) 声子色散关系对横声晶格波、TA 模式单轴应力的依赖性。马氏体 <gamma>'_1 中的声子色散关系与高达 275 MPa 的单轴应力无关。此外,由马氏体<gamma>'_1的单轴应力引起的马氏体<beta>''_1和<alpha>'_1中的声子色散关系与<gamma>'_1中的声子色散关系非常相似。从 10 K 加热到 A_s 时,<gamma>'_1 中的声子色散关系稍微软化。通过施加单轴应力,母相(<beta>_1)中的声子色散曲线在(2/3)q_<max>的q值和布里渊区边界附近稍微软化。马氏体转变被解释为孤子而不是声子的凝聚过程。马氏体相中的孪晶边界是孤子。足够高温度下的奥氏体相由动态孤子组成。需要有限的偏置场来稳定奥氏体中的动态孤子。预马氏体结构由由与成分波动相关的偏置场稳定的孤子组成。马氏体相由通过与马氏体转变本身相关的偏置场绝热稳定的孤子组成。
