Study on the Preparation of TiN Nano-Particles in a Solidified Low Alloy Steel

Abstract:

Article Preview

By using vacuum melting, nitrogen protection and a high molten flow rate during pouring, many nano-TiN particles with the size of 20~100nm are formed during solidification of the alloy steel composed of C0.12- Si0.24 - Mo0.45 - Cr0.35 - V0.2 - Ti0.29 (wt.%). In addition, there are 0.9-1.4μm micron-sized particles separated by a space of 15~40μm. Precipitable TiN particles greatly refine the microstructure of the alloy steel. In this paper, the thermodynamic, kinetic mechanisms and related factors of TiN formation are analyzed.
