Abstract

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 Ti₄₀Ni₆₀ alloy is presented. This phase has precipitated from the massively solidified B2-TiNi. We also report the formation of a faulted structure (A⁹), polytypic to TiNi₃ along with TiNi₃ in melt spun Ti₃₀Ni₇₀ alloy. It is argued that this structure is stabilised due to a specific valence electron by atom ratio.
