[110] TA_1 Phonon Branch and Anomalous 2/3 [110] Elastic Peak in Heusler and B2 Phases of a AuCuZn_2 Alloy
スポンサーリンク
概要
- 論文の詳細を見る
The present study on the [110] TA_1 phonon dispersion relation in a AuCuZn_2 alloy reveals that the lattice instability towards the 18R martensite is characteristic of only the Heusler phase existing stably below about 670 K, which is the disordering temperature to the B2-phase. Anomalous peak appearing near ζ=2/3[110] in the Heusler-phase is also examined by neutron elastic scattering experiments in a wide range of temperature. It is evident that such a peak has no relation to the 2/3-dip on the [110] TA_1 phonon branch observed in the Heusler-phase but it is originated from vacancies existing inherently and regularly in the B2-lattice.
