Abstract
Morphological and crystallographic features of an amorphous state appearing in an initial stage of a eutectoid reaction in a Ti-40 at. % Al alloy have been investigated by transmission electron microscopy. Dark field images with different electron incidences, which were taken by using a part of a halo ring, indicate that the shape of the amorphous-state region is basically a plate, the normal of which is parallel to the [00⋅1] direction of the (Formula presented) structure. In addition, lattice fringes corresponding to the (00⋅2) plane are often observed in the amorphous region. On the basis of these data, it is concluded that a lattice destruction in the amorphous region mainly occurs in the (00⋅1) plane of the (Formula presented) matrix.
