An analysis of crystallization of chromium-molybdenum cast iron with use of the TDA-method is presented in the paper. It has been found that for the cast iron under investigation the eutectic M23C6+gamma is crystalizing independently of M3C+gamma. It has been showen that when increasing the Mo concentration in the cast iron from 2.0 wt. % to 4.0 wt. % the heat being transferred to surrounding due to crystallization (h.t.s.c.) of a primary austenite, of the eutectic M23C6+gamma and the one of the phase transformation austenite -> perlite are increasing as well, while the heat being transferred to surounding due to crystallization of the eutectic M3C+gamma is decreasing. It has been found as well that the result of the simulation of the crystallization of the cast iron are in good correspondence to the experimental TDA - curves as well as to the flux of heat being transferred to surrounding due to crystallization.
