Changes in the structure of the rapidly solidified body-centered-cubic (bcc) solid-solution phase in Ti–Cr alloy were investigated in order to determine whether or not the unique heat-induced amorphization (i.e., SV) actually occurs. Annealing-induced amorphization of the single solid-solution phase was not observed during either ex situ isothermal annealing at 873 K or in situ annealing experiments in HVEM. The previously reported SV may not correspond to the formation of an amorphous phase but could actually be due to the formation of a finely grained polycrystalline structure during the decomposition of the bcc solid-solution phase.
