title: Modulated structures in Ni-Al-Cr alloy.
abstract: The crystal structures of the different modulated and layered martensites in Ni-Al-Cr alloy have been observed. The layered martensite can be well described by the L1(0) lattice with seven-layered or five-layered long-period stacking of {110} close-packed planes of the parent phase. Modulated martensite is considered as a lattice oscillation by shuffling of atoms.
