Results of studies of the high alloy chromium cast iron with boron addition in form of the B₄C phase powder are presented in this paper. The main field of interest is the identification of phases based on the transmission electron microscope study, occurred in this alloy after solidification process. The structure mainly consists of the austenite matrix and M₇C₃ carbide identified as the Cr₇C₃ phase.
