| 中文摘要 | The crystallography of fcc/bcc(bct) martensite transformation, including nucleation and growth, has been discussed from the viewpoint of invariant-line and O-lattice theory. The formation of martensite is accomplished by the immigration of well-defined glissile interface (121)(fcc) type and its misfit dislocations can produce the lattice invariant deformation (LID) on the basis of phenomenal theory of martensitic crystallography (PTMC), however, LID is retarded slightly after the migration of interphase (121)(fcc), i.e. a thin plate-like zone exists without LID in martensite near the well-defined interface. When the temperature reduces to the M-s point, the lattice parameter of austenite matrix is root 3/2 times that of the martensite without LID. This critical condition for spontaneous transformation agrees with that the stack fault energy in matrix is less than zero according to Olson and Cohen's nucleation model. |
