Electron diffraction and high resolution electron microscopy of 63.1 at.% NiAl have shown that the metastable hexagonal Ni[sub 2]Al precipitate, coherent in the B2 matrix phase, transforms concurrently with the martensitic transformation of the B2 NiAl matrix to the L1[sub 0] phase. The Ni[sub 2]Al precipitate that is coherent with the L1[sub 0] phase in monoclinic.
