Explanation of (hhl)f Habit Planes in Ferrous Alloys

Abstract

We give a possible explanation of the remarkable habit-plane measurements reported by Kajiwara for Fe-Ni-Mn alloys. Examining small, thin (early-stage), martensite plates, Kajiwara found that all habit-plane normals fall on the (hhl)f line, spanning about 25 degrees from approximately (114)f to (223)f. Despite numerous suggested modifications, the crystallographic theories of Wechsler-Lieberman-Read and Bowles-Mackenzie fail to predict habit planes on the (hhl)f line, let alone variations along the line. Kajiwara invoked Suzuki's prism-matching theory, which contains an anisotropic interface distortion, an adjustable parameter contrary to more recent measurements. Our explanation arises from another, more general approach: inclusion theory, which includes crystallographic-theory predictions as the zero-elastic-strain-energy limit.
