It was found that the eutectoid transformation products from β-Ti(H) were consisted of δ hydrides and α-Ti,forming a micro-polycrystalline aggregate, while γ hydride was precipitated from α-Ti(H) directly. The atomic structure of these microcrystals were carefully delineated by HRTEM, showing that there may be ten variants of α-Ti around δ hydrides, which can keep two definite crystallographic relationships with α-Ti. The shear mechanism of the eutectoid transformation is discussed.
