Crystallography of Lath Martensite in Steels

open access: yesMaterials Transactions, JIM, 1992
The double lattice invariant shear version of the phenomenological theory, has been used to explain all the known crystallographic features of lath martensite. When the lattice invariant shear systems are taken to be rational slip systems in martensite with slip directions along [111̄] and [11̄1̄], the habit plane solutions converge to an (hhl) hab ...
