Research Abstract

The pinning effects of carbide particles on the grain growth of ferrite were studied in Fe-0.1C-0.0005B and Fe-0.1C-0.09V alloys. The number and size distribution of carbide particles were determined on multiple sections in distinction of grain facesm edges and corners. The numbers of particles in contact with each type of grain boundary site were several times greater than those calculated assuming random distribution. Taking this into account, the final grain size is predicted to be in fair agreement with measured ones.
