Abstract Scope Diffraction elastic constants are used to convert lattice strain measurements to macroscopic stress values. In this work, we present a new method for calculating diffraction elastic constants and apply this method to the example of biaxially strained ferritic BCC (body centered cubic) steel. We incorporate EBSD (electron backscatter diffraction) data measured from biaxially strained samples into a finite element model (OOF2) and elastically strain the model to measure the diffraction elastic constants. In addition to providing values for the diffraction elastic constants, the EBSD based finite element model provides insight into the source of the experimentally observed non-linear behavior in the (211) reflection in BCC steels. The non-linear behavior is largely due to two clusters of grain orientations with different stiffness along the normal direction of the sheet.
