Formation Inhomogeneity of Deformation Martensite in Rolled Foil of Fe-28%Ni-5%Mo Alloy under Bending

摘要

In this work, we study inhomogeneous martensitic transformations at low-temperature deformation via wrapping of rolled polycrystalline Fe-28%Ni-5%Mo (at %) alloys on a mandrel in two directions: along the rolling direction and transverse direction. X-ray diffraction reveals that γ ⇒ a transformation at low-temperature deformation under bending on the opposite sides of the sample is localized in different groups of grains.
