抄録

The morphology and crystallography of the Ti2Pd phase with C11b structure precipitated in B2 parent and B19 martensitic matrices in a Ti-rich Ti-Pd shape memory alloy have been investigated by transmission electron microscopy. Three Ti2Pd variants are recognized in the specimen aged above the Af temperature, i.e., in the B2 matrix. On the other hand, four Ti2Pd variants are confirmed in the specimen aged below the As temperature, i.e., in the B19 matrix. The ori.entation relationship between the Ti2Pd precipitate and each matrix is consistent with the number of Ti2Pd variants. The Ti 2Pd precipitates in the B2 and the B19 matrices have disk and polygonal plate shapes, respectively. The c-axis of Ti2Pd precipitate in the B2 matrix is perpendicular to the disk surface. On the other hand, that in the B19 matrix is parallel to the plate surface. These differences are well explained by the magnitude of the coherent strain.
