Abstract
In the Ti-8%Mn alloy brine quenched from 950°C, ω′ (which gives diffuse diffraction spots at the same positions as ω) and α″ (fcc martensite) phases besides retained β phase were observed by electron microscopy. In this report, the authors studied the structure change of these phases by aging treatment at 450°C and the structure of the precipitated ω. According to the result of the electron microscopic observation on the aged materials, ω′ grows to ω and α″ decomposes into α and β. The crystal structure of the ω phase is hexagonal and its c axis is parallell to ⟨111⟩β. It is observed that the precipitated ω phase has a rod shape which elongates along ⟨111⟩β and its longitudinal size is approximately 300 Å. The α phase is observed in the specimen aged for 60 min and it has Widmansttaten structure. The orientation relationship between β phase and α phase is [0001]α\varparallel[110]β.
