STRAIN INDUCED PRECIPITATION OF Ti(V)N(C)IN HIGHCARBON STEEL

摘要

The precipitation of Ti（V）N（C）in high-carbon steel PD3 during thermomechanicol treatmentat austenitic temperatures after deformation has been observed.The average size ofTi（V）N（C）particles may reduce with the increase of strain and the decrease ofthermomechanical treatment temperature,and vise versa.The growth of Ti（V）N（C）particlesat 920°C is found to be controlled by the interface reaction between precipitated particles andmatrix.
