Improved models of retained austenite transformation in trip steels require experimental data of local strain and transformation evolution. Microscopy tools, such as electron backscatter diffraction (EBSD), that can be used to monitor transformation at the relevant length-scale are often incompatible with digital image correlation (DIC) techniques that are required to determine local deformation. In this paper, the viability of using forescatter detector (FSD) images as the basis for the DIC study is investigated. While the method does not give subgrain resolution, the data is easy to obtain and provides a natural set of complementary information for the EBSD analysis. Results are presented for tensile tests of an 1180 trip steel.
