The morphology of lath martensite: a new perspective

Blog Article

A mathematical framework is proposed to predict the new balance 990 v3 red features of the (5 5 7) lath transformation in low-carbon steels based on energy minimisation.This theory generates a one-parameter family of possible habit plane normals and a selection mechanism then identifies the (5 5 7) normals as those ellakai arising from a deformation with small atomic movement and maximal compatibility.While the calculations bear some resemblance to those of double shear theories, the assumptions and conclusions are different.Interestingly, the predicted microstructure morphology resembles that of plate martensite, in the sense that a type of twinning mechanism is involved.
