摘要：

The effects of titanium and nitrogen additions in 0.16% C - 1% Mn high-strength low-alloy steel and of the rate of crystallization cooling on precipitation of TiN nitride and of complex TiN-CaS particles are studied. The processes of formation and growth of TiN and TiN - CaS particles in the mushy zone are analyzed using a thermodynamic model of diffusion growth. The thermodynamic computations are checked experimentally. The steel is controlled for presence of coarse TiN inclusions.
