     particles of ticn and tic were produced by means of self-spreading high temperature synthesis and after covering with metal protector were studied in order to be applied for modification of molten steel. after microstructure characterization the ticn nano- and micron-sized particles were selected for modification of castings of p265gh steel and the microstructure and mechanical properties of the modified steel were studied and compared with those of the steel without modification. the data from microstructure-properties analysis of the modified steel showed that the steel treated with nano- and micro-sized particles has significantly refined microstructure, increased strength and hardness and improved elongation in comparison with the non-modified castings.
