چکیده انگلیسی
The spatial orientation distribution and crystal orientation relationships (ORs) between a butterfly-type martensite (αâ²) plate and its austenite matrix (γ) in Fe-30% Ni alloy were investigated in detail. One αâ²-γ interface of the αⲠplate mainly exhibits a G-T (Greninger-Troiano) OR, while the other side shows both Kudjumov-Sachs and G-T ORs. It is proposed that the difference between the two sides arises due to a change of the accommodation process for transformation strain during the growth of αâ². Moreover, orientations inside the αⲠplate continuously change from the one αâ²-γ interface to the other. A similar orientation change is observed in the γ matrix but only on one side of the plate. These orientation gradients have a common rotation axis and are explained in terms of dislocation inheritance during the growth of the αⲠplate. Based on the local changes of ORs at αâ²-γ interface and the orientation gradients inside αⲠand γ, the αⲠformation process is discussed.
