The characteristic form of a phase, which always exists as a pair of phites when produced by decomposition of the matrix of β' phase, was examined by using an embossing method and SEM observation. A prominent feature of the α phase was utilized to determine the habit plane of α phase to the matrix plane. A straight line appeared at the center of the triangular α phase as one of the feature, and this center line was almost parallel to the (002) band of SEM-ECP from the β' matrix. At the (001) plane of β' matrix, there are two kinds of α phase that could be divided by the inclination angle to the (011) band of SEM-ECP, and they were separated away by an angle of about 4゜ each other. At the (011) plane of β' matrix, each plate of α phase pair was inclined about 7.3゜ from the (011) band of SEM-ECP from the β' matrix. From the results mentioned above, it is concluded that the habit plane of α phase to β' matrix exists near {5, 27, 29}m Plane of the matrix.
