Abstract
|
|
|
|
| The Ni-rich Ni-Al beta2 phase (CsCl structure) exhibits the precipitation of a metastable Ni2Al phase, which is closely related to an underlying lattice instability of the [111] phonon branch in the beta2 phase. The Ni2Al precipitates undergo both the Bain distortion and twinning together with the martensitic transformation of the beta2 matrix. The resulting structure of the Ni2Al precipitates in the martensite is presented and discussed. |
