The metastable microstructures in two rapidly solidified Ni rich Ti-Ni alloys are studied. A first report of the presence of a cubic phase with three times the lattice parameter of B2-TiNi in melt spun $Ti_{40}Ni_{60}$ alloy is presented. This phase has precipitated from the massively solidified B2-TiNi. We also report the formation of a faulted structure $(A^9)$, polytypic to $TiNi_3$ along with $TiNi_3$ in melt spun $Ti_{30}Ni_{70}$ alloy. It is argued that this structure is stabilised due to a specific valence electron by atom ratio.
