Phase-transformation and recrystallization behavior of Ti5553 alloy have been studied using dilatometer. Ti-5553 alloy was cast, homogenized and forged and rolled. As deformed material when heated in a dilatometer showed both expansion and contraction during heating. While expansion is attributed to alpha to beta transformation, contraction is observed in a temperature range over which no known phase-transformation occurs in this alloy and hence cannot be attributed to any known phase-transformation. Amount of contraction is found to be function of orientation of the dilatometer sample with respect to the rolling, normal and transverse directions. Contraction is believed to be the result of either texture change involving recrystallization of the phases, or residual stress assisted anisotropic phase transformation.
